How to bleed the brake system on a Chevrolet Niva alone

How to bleed the brakes on a Chevrolet Niva yourself

Experienced car owners know that the brake fluid on a Chevrolet Niva needs to be changed every fifty thousand kilometers, but at least once every 2 years. So, if the car reacts poorly to pressing the brake pedal, this indicates that there is moisture or air in the system. Consequently, it is necessary to bleed the brake system in the Chevrolet Niva, completely replacing the brake fluid. Foreign elements appear there due to the natural chemical decomposition of some components of the brake fluid and the high temperature generated during braking. The following are considered signs of air penetration into the hydraulic drive:

Note. When pumping a hydraulic drive is directly related to the repair of one of the circuits, and the serviceability of the second circuit is known, it is permissible to pump only the circuit being repaired.

The process of bleeding the hydraulic drive in a Chevrolet Niva is identical to replacing the brake fluid. The only difference is that the condition for the end of pumping of the working cylinder is the end of the release of air from the tube, and not the appearance of new brake fluid.

Thus, the car owner needs to bleed the brakes when observing any of the following signs:

Bleeding the brakes of a Niva Chevrolet: step-by-step instructions

Air, compared to liquid, is more easily compressed, as a result of which the presence in the line rapidly reduces braking performance. In Chevrolet, the brake mechanism is equipped on a 2-circuit principle. The latter ensures reliability during depressurization. Thus, one circuit includes the working cylinders of the tires (right rear, left front), while the second circuit includes the left rear, right front. The pumping sequence involves bleeding air bubbles using a special fitting.

Signs of air penetration are as follows:

• increased pedal travel, softness appears when pressing the brake pedal;
• a smooth decrease in pedal travel and a simultaneous increase in rigidity when pressing the pedal (before pumping, depressurization must be identified and eliminated).

Activities must be carried out with a partner on an equipped area - an overpass or inspection hole. The tire casing bleeder fittings should be thoroughly cleaned of dirt. First, you have to get rid of the air in one brake circuit, starting with the rear right tire housing and ending with the left tire block at the front. Meanwhile, air should be removed when the rear wheels are loaded.

When bleeding the brakes in a Chevrolet Niva with a rear mounted section, it is worth loading the pressure lever of the brake located at the rear. Now you need to insert a screwdriver into the middle of the piston lever and the pressure regulator piston.

For work, prepare tools and consumables in advance:

• union (split) nut head for 10;
• union (split) nut head for 8;
• container for TJ (1-2 liter);
• rubber bulb;
• brake fluid;
• brake fitting;
• aerosol VD-40;
• rags;
• hose.

1. Remove the dust cap from the fitting (to make it more convenient, it will fit to remove the rear tire).
2. Wet the fitting with WD-40, then put a wrench on it and tighten the tightening bolt.
3. Pull the rubber tube onto the fitting. Then lower its end into the prepared container, partially filled with TJ.
4. Meanwhile, your partner needs to press the brake 3-4 times every 1-2 seconds, thus holding the pedal in the pressed position.
5. Next, you need to take the head 8 and unscrew the fitting half or ¾ of a turn. At the same time, air bubbles, as well as some of the brake fluid, will escape into the container; the brake pedal will go to the floor.
6. The next step is to tighten the fitting, after which the assistant can release the brake.
7. Repeat the operation performed to bleed the Chevrolet. Perform the action until air bubbles stop coming out of the tube, but only TJ.

In the same way, you need to get rid of air using the upper fitting on the front tire on the left. To remove bubbles that form in another circuit, pump the tire in the following order: left - rear - front right tire.

Bleeding the brakes is especially necessary if any of the following symptoms occur:

• decreased braking performance;
• feeling of a cotton pedal;
• Each time you press the pedal, more force is required.

1. Remember that hydraulic fluid is poisonous. If it gets on exposed skin, wash off immediately with plenty of water. If liquid suddenly gets into your eyes or is accidentally swallowed, call an ambulance immediately.
2. Some types of liquid are flammable and can ignite if they come into contact with a hot substance or open flame. During work, it is better to play it safe, considering that any liquid is flammable, in order to react in time and take all precautions.
3. Hydraulic fluid is considered aggressive towards plastic elements and paints. If liquid gets on the painted surface of the body or on plastic parts, it should be washed off immediately with plenty of water.
4. Liquid has the ability to absorb moisture from the air, therefore it is hygroscopic. Excess moisture content reduces the boiling point to unacceptable parameters. This leads to an unsafe reduction in braking performance.
5. Old liquid cannot be reused, because it may contain a lot of dirt and foreign particles. If you need to add or replace fluid, use only the recommended one.

How to bleed the brakes on a Chevrolet Niva yourself

An assistant is required to bleed the brakes.

Meanwhile, the choice of the sequence of bleeding the brake lines is not significantly important, since each caliper has its own connection to the main cylinder.

The car must be placed on a level surface, in first or reverse gear. Then it is advisable to place wheel chocks or a device made of boards under the wheels. Next, you need to check the brake fluid level in the cylinder reservoir, which is located under the hood (between the windshield and the air filter housing). After pumping out the old fluid from the tank, add fluid to the max mark on the tank. The preparatory activities have been completed, you can proceed directly to work.

It is not so easy to determine at random when a complete replacement of the brake fluid on a Chevrolet Niva has been carried out. It’s appropriate to proceed from the following volumes: if the car has ABS, you will need 0.5 liters for each caliper; without ABS, 0.4 liters is enough. Such figures are given with a slight margin so that the replacement is carried out efficiently and the conditions for the new fluid replacement are standard.

Replacing brake fluid

If a replacement is needed, then you should study the structure of the brake system of your vehicle. Changing ABS brake fluid is very different.

Suppose without an ABC or a hydraulic accumulator, the pump and the ABC hydraulic valve block are located in one unit, then you can replace the fluid with your own hands. With integral ABC, it would be more correct to go to a service station.

Work must be carried out on each circuit of the brake system. The tools you will need are an empty bottle and a flexible hose. Additionally, you need to have a set of keys to work.

It all starts with the wheel that is furthest from the brake cylinder. First you need to drain the fluid from the brake reservoir and pour new one into it. Next, unscrew the fittings on each brake cylinder and wait until the old brake fluid drains out.

When a new one starts to leak, tighten the fitting. If the car has a diagonal system of contours, the process must begin with the right rear wheel, then the left front, then the rear left, and finally the front right.

With a parallel circuit, the sequence is:

Replacement must be carried out on removed wheels. If there is a hole, the work will be much easier. As a last resort, you can do all this with a jack, removing the wheels one by one.

At the same time, you can visually check the condition of the car, check the suspension elements and shock absorbers.

Be sure to bleed the brakes after all work. Look in the reservoir; you may need to add new fluid.

It is necessary to check the effectiveness of the brakes after replacing the brake fluid. We carry out the test on a dry road at various speeds. The car should stop smoothly and maintain directional stability. Have a good trip and no breakdowns.

How to bleed ABS brakes yourself

Good day, dear car enthusiasts! There is most likely no driver among us who has not at least once experienced a feeling of helplessness at the moment of braking. When the car continues to move, and not at all in the direction the driver wants. Skid.

Fortunately, engineering does not stand still. The modern driver is armed with a system such as ABS. Let's take a closer look at the system and see if it is possible to bleed ABS brakes yourself.

Bleeding the brakes without an assistant

ABS (Anti-lock Braking System) is an anti-lock braking system that prevents the wheels from locking during emergency braking.

The main task of ABS is to regulate the speed of rotation of all wheels. This is done by changing the pressure in the car's brake system. The process occurs using signals (pulses) from each wheel sensor that enter the ABS control unit.

The principle of operation of the anti-lock braking system The contact patch of the car's wheels is relatively immobile to the road surface. According to physics, the wheels are affected by the so-called. static friction force.

Taking into account the fact that the static friction force is greater than the sliding friction force, ABS effectively slows down the rotation of the wheels at a speed that corresponds to the speed of the car at the moment of braking.

Anti-lock braking system design Let's list the main components of ABS:

• sensors installed on the wheel hubs of a car: speed, acceleration or deceleration;
• control valves installed in the line of the main brake system. They are also components of the pressure modulator;
• ABS electronic control unit. Its task is to receive signals from sensors and control the operation of valves.

Bleeding an ABS brake system will require you to have certain technical skills. In addition, it will not be superfluous to first study the manual on the design and maintenance of the brake system of your car.

Features of bleeding brakes with ABS

• in cars that have a hydraulic valve block, a hydraulic accumulator and a pump in one unit, replacing the brake fluid and bleeding the brake system with an anti-lock braking system is carried out in the same way as bleeding the brakes on a car without ABS, you need to turn off the system by removing the fuse. Bleeding of the circuits is carried out with the brake pedal pressed, the RTC bleeder fitting must be unscrewed. The ignition is turned on and the pump expels air from the circuit. The bleeder screw is tightened and the brake pedal is released. An extinguished malfunction light is evidence that your actions were correct.
• Bleeding the brake system with ABS, in which the hydraulic module with valves and the hydraulic accumulator are separated into separate units, is carried out using a diagnostic scanner to retrieve information from the ABS ECU. It's unlikely you have one. Therefore, bleeding of brakes with ABS of this type should most likely be done by you at a service station.
• Bleeding the brake system with ABS and electronic activation systems (ESP or SBC) is carried out only under service conditions.

It is important! It should be remembered that the pressure in the brake system reaches 180 atm. Therefore, in order to prevent the release of brake fluid, before disconnecting the brake lines on any system with ABS, it is necessary to discharge the pressure accumulator. To do this, with the ignition off, press the brake pedal 20 times.

Technology for bleeding the brake system with ABS

Bleeding brakes with ABS, like bleeding a conventional brake system, is done with an assistant. Turn off the ignition (position “0”). Disconnect the connectors on the brake fluid reservoir.

Front wheel brakes:

• put the hose on the bleeder fitting;
• open the fitting back;
• the brake pedal is pressed all the way and held in the depressed position;
• we observe the release of an “aired” mixture;
• tighten the fitting and release the pedal.

Rear right wheel brake:

• put the hose on the bleeder fitting, unscrew it one turn;
• press the brake pedal all the way, turn the ignition key to position “2”. In this case, the brake pedal is held in the pressed position;
• a running pump will expel air from the system. That is, as soon as the brake fluid begins to come out without air bubbles, close the fitting and release the brake.

Rear left wheel brake

• The hose is put on the fitting and unscrewed 1 turn;
• DO NOT press the brake pedal;
• a working pump pushes out the “aired” mixture;
• press the brake pedal halfway and tighten the fitting;
• release the pedal and wait until the pump stops completely.

In reverse order: ignition key to “0”, connect the connectors to the brake fluid reservoir, check the brake system for leaks (see ABS fault indicator).

Good luck with bleeding your ABS brakes.

Design of the working hydraulic system

In order to increase the reliability and safety of control, the hydraulic brake system of the Chevrolet Niva is built according to a dual-circuit diagonal design. The first hydraulic drive circuit drives the front right and rear left wheels, and the second drive drives the front left and rear right wheels. Thus, controllability is maintained in the event of failure of one of the hydraulic drive circuits. The hydraulic braking system includes:

What you need to know about bleeding the system in a Chevrolet

1. Hydraulic fluid contains poison. If it comes into contact with exposed skin, wash it off immediately with a large stream of water. If suddenly the substance gets into your eyes, or, worse, you swallow it, you should seek medical help.
2. Some types of hydraulic fluid are flammable and can therefore catch fire if they come into contact with hot elements or an open flame. During your work, you should always remember this in order to take appropriate precautions in time.
3. The liquid is aggressive to plastic parts and paint. If the substance gets on the surface of a painted body or plastic, immediately wash it off with a large stream of water.
4. The liquid is hygroscopic, that is, it can absorb moisture from the air. Excess moisture content lowers the boiling point to unacceptable levels, resulting in an unsafe reduction in braking performance.
5. Used hydraulic fluid cannot be reused. It is most likely already contaminated. If you need to add or replace fluid in the system, use only the recommended type.

Tools:

• Split spanner 10 mm
• Split spanner 8 mm
• Rubber bulb
• Capacity for brake fluid 1-2 l.

Parts and consumables:

• Brake fluid
• Rags
• Aerosol lubricant type WD-40
• Brake fitting
• Bleeding hose

Bleeding the brakes is necessary when replacing brake fluid, as well as to remove air that has entered the hydraulic drive during the repair or replacement of individual components of the brake system. Air trapped in the hydraulic drive causes an increase in the free play of the brake pedal (the pedal becomes “soft”) and significantly reduces the effectiveness of the brakes.

– when you press the pedal once, the pedal travel increases, its “softness”;

– with repeated pressing of the pedal – a gradual decrease in the pedal stroke with a simultaneous increase in its “hardness”. Before bleeding the hydraulic drive, it is necessary to identify and eliminate the cause of depressurization.

We carry out the work with an assistant on an inspection ditch or overpass. Thoroughly clean the wheel cylinder bleeder fittings from dirt. We remove air first from one brake circuit, starting from the wheel cylinder of the right rear wheel and ending with the cylinder block of the left front wheel. We remove air with the rear wheels loaded.

When bleeding the brakes on a car with the rear part suspended (for example, on a lift), it is necessary to load the rear brake pressure regulator, insert a screwdriver between the pressure regulator piston and the piston lever.

1. Remove the protective cap from the bleeder fitting of the wheel cylinder of the right rear wheel.

2. We put a hose on the head of the fitting, lowering its free end into a vessel partially filled with brake fluid.

3. An assistant presses the brake pedal three to four times at intervals of 1-2 seconds and holds the pedal down. Using the “8” wrench, unscrew the bleeder fitting 1/2 - 3/4 turn. In this case, air and part of the brake fluid are forced into the vessel, and the pedal is lowered to the floor (air bubbles are clearly visible in the vessel with the liquid).

We tighten the fitting and only after that the assistant can release the brake pedal. We repeat the bleeding operation until the release of air bubbles from the hose stops and only brake fluid comes out. In this case, air and part of the brake fluid are forced into the vessel, and the pedal is lowered to the floor (air bubbles are clearly visible in the vessel with the liquid).

4. Then remove air from the cylinder block of the left front wheel.

5. Remove the protective cap from the lower bleeder fitting of the cylinder block of the left front wheel.

6. Putting a hose on the head of the fitting, lower its free end into a vessel partially filled with brake fluid. We remove air through the lower fitting of the cylinder block.

7. In the same way, remove air through the upper fitting of the cylinder block of the front left wheel.

8. To remove air from another circuit, we bleed in the sequence: left rear - right front wheel.

When removing air from the system, you need to monitor the fluid level in the master cylinder reservoir and add it if necessary.

If there is no air in the system, the brake pedal should be “hard”, i.e. when pressing, go no more than half the distance to the floor.

When removing or replacing elements of one of the circuits, only this circuit must be pumped. When removing or replacing the master brake cylinder, pressure regulator, or a drop in the level of brake fluid in the reservoir, resulting in air entering the hydraulic drive, it is necessary to completely bleed the brake system, i.e.

Brake fluid Niva Chevrolet, choice

Let's take the following fact as an axiom - almost NONE of the leading manufacturers of pads or brake components make their own brake fluid. It is made either by chemical concerns or manufacturers of auto chemicals and oils. Example. Everything that is in jars of the TRW, BMW, ATE brands is made by manufacturers ROWE, BASF, Pentosin, ELF-TOTAL. Therefore, when I selected suppliers, I was guided by the following thought. A well-known company that deals with brake systems simply will not disgrace itself and sell a low-quality product in its own name. That's why I settled on Bosch, TRW, Brembo products. To fully pump the system of our car, 1 liter of product is enough. There is still some left for refilling.

Purpose and operation of the pressure regulator

The pressure regulator (“sorcerer”) is designed to prevent the car from skidding during sudden braking. This is achieved due to the fact that the rear wheels begin to brake after the front ones. The time delay is provided by the regulator lever, which, when the car brakes sharply (the nose drops and the rear rises), pulls the piston in the regulator cylinder and closes the fluid supply channel to the working cylinders of the rear wheels.

In this case, the rear brakes do not work and the wheels spin until the rear of the car drops back. Thus, the “sorcerer” automatically regulates the fluid pressure in the rear cylinder path in inverse proportion to the load on the rear axle. In addition, it increases the braking efficiency of an empty vehicle when the load on the front axle is higher than on the rear.

This work must be carried out at every maintenance and after repair of the rear suspension.

How to Bleed the Brakes Alone in the Field. All methods of bleeding brakes. Possible problems Part 1

Screw the plugs into the master cylinder ports and tighten them. Tighten the plug, then have an assistant slowly release the brake pedal and wait about 3 seconds. Repeat this procedure once. Repeat the procedure for the front of the second circuit master cylinder. To prevent fluid from escaping from the cylinder and, therefore, air entering it, before removing the plugs, have an assistant lightly press the brake pedal approximately 30 mm and hold it in this position.

Remove the plugs from the brake pipes and make sure that both pipes are filled with fluid; if not, add liquid to them. Quickly remove one of the master cylinder plugs and hold the brake pedal as described in the previous paragraph, connect the brake pipe and tighten the connecting nut to the torque specified in the Specifications. Repeat the procedure on the second master cylinder port, then wash off the spilled fluid.

We remove air first from one brake circuit, starting from the wheel cylinder of the right rear wheel and ending with the cylinder block of the left front wheel. We remove air with the rear wheels loaded. When bleeding the brakes on a car with the rear end hanging up, for example, on a lift, you need to load the rear brake pressure regulator, insert a screwdriver between the pressure regulator piston and the piston lever.

Remove the protective cap from the bleeder fitting of the wheel cylinder of the right rear wheel. We put a hose on the head of the fitting, lowering its free end into a vessel partially filled with brake fluid.

An assistant presses the brake pedal three to four times at intervals of s and holds the pedal down. In this case, air and part of the brake fluid are forced into the vessel, and the pedal drops to the floor; air bubbles are clearly visible in the vessel with the liquid.

Repair of VAZ 21213#Problem with brakes.

We tighten the fitting and only after that the assistant can release the brake pedal. We repeat the bleeding operation until the release of air bubbles from the hose stops and only brake fluid comes out.

Brake fluid selection

All brake fluids except DOT 5 use polyethylene glycol in combination with boric acid polyesters as a base, while DOT 5 uses silicone as a base. Brake fluids DOT 3, DOT 4 and DOT 5.1 have the same base and can be interchanged without any problems, at least within the same manufacturer.

Some manufacturers use polyalkylene glycol as a base for the production of DOT 3 (and possibly other grades). Information on the incompatibility of liquids based on polyethylene glycol and polyalkylene glycol could not be found anywhere, and knowledge of chemistry as a first approximation allows us to state that such a mixture will work no worse than the original components.

It should also be separately mentioned that some brake fluids are designed to work in the braking systems of cars with ABS (anti-lock braking system), most often they are marked with the addition of the designation “ABS”, for example DOT 5.1/ABS, or this is indicated separately on the packaging.

You should not mix brake fluids, even of the same class, if one of them is designed for ABS and the other is not, i.e. mix, for example, DOT 5.1 with DOT 5.1/ABS, because these fluids have slightly different chemical compositions of additives to reduce aeration (prevent the formation of bubbles) in the ABS system and there is no guarantee that as a result you will have a brake fluid that is chemically and physically stable system.

If you have a car with ABS, then you cannot use DOT not designed for ABS or even just add it to another DOT for ABS, which is understandable. If we are talking about a bicycle and hydraulic bicycle brakes, then you can use any DOT, rated for ABS or not, preferably without mixing them.

When glycol-based fluids (DOT 3, DOT 4 or DOT 5.1) are mixed with silicone-based DOT 5 fluid, a chemical reaction occurs resulting in a compound that does not meet any brake fluid requirements and is aggressive to the seal material.

Do not mix DOT 3, DOT 4 or DOT 5.1 with DOT 5 silicone fluid! A complete replacement of glycol brake fluid with silicone is possible (DOT 3, 4, 5.1 to DOT 5), but this requires first cleaning and thoroughly drying the entire brake system of old brake fluid. At the same time, there is no guarantee that the material of the brake system seals will be resistant to silicone fluid, although the chances of damage to the seals by silicone fluid are quite small, because Silicone based fluid is not as aggressive as glycol based DOT. The advantages of such a replacement in the case of a bicycle are extremely unclear.

Replacing silicone brake fluid with glycol is practically impossible (DOT 5 to DOT 3, 4 or 5.1), no matter how much you flush the entire system beforehand, because glycol DOT is very aggressive and if the brake system elements were not originally designed for it, then most likely In all, the brake system seals will be destroyed. https://www.drive2.com/l/457842415315760117/

How to Bleed Brakes (3 Main Mistakes in Bleeding Brakes)

Knowing how to bleed brakes will be useful to any driver, since the procedure is not very complicated, and it must be performed after many manipulations related to the brake system. So why waste extra money once again by sending your car for service when you can pump the brakes alone?

By following the instructions and avoiding the mistakes described below, it is quite possible to remove the air from the brakes yourself, with or without ABS. Bleeding brakes with ABS is by no means more difficult, but still it is a separate topic worthy of its own article.

It is only worth noting that if there is an anti-lock braking system with ESP and SBC modules, then the path lies with a service that has the necessary equipment.

You can pump the brakes yourself, or you can have an assistant, whose task is to press the brake pedal on command. The procedure for bleeding the brakes should be found in the manual for a specific car.

If the diagram is not indicated, then bleeding is done in the form of the letter Z. This means that you need to pump in this order: right rear - left rear - right front - left front wheel.

To bleed the brakes, you will need a brake fluid container and a clear rubber hose.

First you need to get convenient access to the brake system bleeder fittings. To do this, you can put the car on a lift or platform and remove all the wheels. Don’t forget to clean the fittings near each wheel from dirt and pour a little “brake fluid” into the prepared container.

Instructions:

1. Pour new brake fluid into the master cylinder reservoir.
2. Connect the hose to the fitting, and lower the other end into a container with brake fluid.
3. Command your assistant to press the pedal several times and hold it depressed until the fluid flows.
4. Unscrew the fitting and the liquid will flow into the container you prepared. Carefully monitor the fluid level in the tank and add as necessary.
5. Repeat the previous 2 steps until the brake fluid comes out clean without air bubbles, and tighten the fitting.
6. Repeat the same procedure on the remaining wheels.

Bleeder fitting on the brake caliper. A hose is put on it

The brakes are bled when it is necessary to remove air from the brake system. This often happens when replacing brake fluid, which is done approximately every 50-60 thousand km. mileage or once every 2 years.

It is also necessary to bleed the brakes after repairing the brake system: replacing the master cylinder or vacuum brake booster. The need for bleeding also arises when depressurization occurs due to damage to the hoses, or when the liquid in the expansion tank drops below the minimum mark.

The pedal will indicate that you need to bleed the brakes - it will become soft and begin to sink. And the brakes themselves will become more sluggish. However, this could also indicate a more serious problem with the brake rotor or pads. So, if bleeding does not help, perhaps you should still contact a specialist - brakes are no joke!

How to pump the brakes with a partner has already been described above. What to do if there is no such thing nearby, but you need to bleed the brakes? You can get out of this situation in several ways:

• You can bleed the brakes alone if you have a gas stop. The meaning is the same as when pumping with an assistant, only instead of him the gas stop will press on the pedal. Therefore, you need to press the pedal several times, keep it pressed, set the stop and begin to bleed the brake fluid. When the fluid begins to flow, the stop will begin to push the pedal to the floor to the limit.
• bleeding the brakes with a syringe. You need to hermetically embed the syringe into exactly the same lid as on the tank. Then, having first filled the syringe with brake fluid, replace the regular cap with this device, unscrew the fitting, place a container and apply pressure with the syringe.
• another method with a modified lid. You need to insert a car nipple into a cap similar to the one installed on the tank. Then put the lid with the nipple on the tank, then put one end of the hose with a connection clamp on the lid, and the other on the spare chamber, inflated to no more than 1 atmosphere. Open the fitting and bleed out the liquid with air bubbles.

DIY brake bleeding device

These are the main ways to bleed brakes without an assistant, but many drivers have their own methods, which, however, are not very different from the above.

Before you start bleeding your brakes, it's worth considering three common mistakes that are made when doing this. Therefore you CANNOT:

1. Mix different brake fluids. If you mix mineral brake fluid with glycol, it will damage the rubber cuffs of the hydraulic drive and clog the system with clots. It is also not recommended to mix liquids of different classes (DOT 3, DOT4, DOT5), since they have different boiling points and this will reduce their characteristics.
2. Allow the brake fluid level to drop significantly. If you do not monitor the brake fluid level in the reservoir and it drops below the minimum level, air will enter the brake system.
3. Create high pressure in the brake reservoir. When pumping the brakes yourself, do not overdo the pressure created in the reservoir, otherwise it may rupture. Recommended pressure is 0.8 atmospheres.

The essence of the procedure is the same as in the first option. You should unscrew the bleeder fittings one by one to get rid of excess air. Experts recommend carefully monitoring the fluid level in the tank and, if necessary, adding it to the required volume.

Brake pads for Chevrolet Niva

The front wheels of the Niva Chevrolet use disc brakes, and the rear wheels use drum brakes. Accordingly, the pads on them are different. Pads are the main working part of the brakes, which carry the most load and wear out the fastest. If the car is used intensively, the condition of the pads should be checked at least once every six months. Today there are many different domestic and foreign manufacturers of pads for Niva-Chevrolet cars.

They differ in price, material, service life. The so-called “Kevlar” pads from the Japanese company NIBK are considered the most effective and “cool”. They are made using modern nanotechnology from a compound that is equally effective in various operating modes. The advantages of this pad model include:

The only disadvantage of these pads is the high cost, but the price corresponds to the quality.

If you need information about replacing front pads, this is the place for you.
