Replacing the front brake cylinder of a VAZ 2107

Replacing the rear brake cylinder on a VAZ 2101-2107

If the rear brake cylinder on a VAZ 2101-2107 begins to jam or perform its function ineffectively, it should be replaced with a new one. To do this we need the following tool:

1. Split wrench for unscrewing brake pipes
2. Penetrating lubricant
3. 10mm socket with ratchet or regular 10mm wrench

So, the first step is to perform some preparatory procedures, which are listed below:

After this, the rear brake cylinder becomes free and its location is shown in the photo below:

So, first you need to spray the brake pipe with penetrating lubricant, and then unscrew it:

After this, you need to unscrew the two bolts securing the cylinder, which are located on the reverse side:

The most convenient way to do this is with a socket and ratchet:

And now you can safely remove the VAZ 2101-2107 brake cylinder from the reverse side, as is clearly demonstrated in the photo below:

Next, we buy a new cylinder, the price of which for all classic models is about 300 rubles apiece. If you change a pair, you will have to buy two pieces and spend 600 rubles. Installation is carried out in reverse order.

If necessary, after replacement, bleed the brakes if there is air in the system.

If you notice a brake fluid leak that appears on the inside of the rear wheels in the form of smudges, most likely the problem lies in the brake cylinder and it should be replaced. The reason could be a simple damage to the rubber cuffs. When sealing the brake pistons, a complete replacement of the brake cylinder is also required. Prepare a brake pipe wrench and new brake fluid. Ensure that your partner helps you.

To begin, slightly raise the car using a jack. On the side to be repaired, remove the wheel and brake drum to give yourself full access to the brake cylinder.

Cylinder replacement

1. After the brake drum is removed, take some gasoline and wash the internal cavity to remove dirt and dust.
2. After this, take a special wrench and unscrew the tube mounting fitting on the back of the brake flap. Plug the freed hole with a plug or any other plug, otherwise the brake fluid will leak out completely. If the fitting cannot be unscrewed, and it is stuck very firmly, then you will have to break it and subsequently replace the brake pipe with a new part.
3. Then unscrew the two mounting bolts of the brake cylinder itself.
4. Disengage the cylinder from the pads and remove it.

During the repair process, check the condition and quality of the rubber cuffs. As practice shows, replacing the cuffs has virtually no effect - brake fluid leaks do not stop. Therefore, if the cuffs are damaged, it is better to completely replace the mechanism with a new cylinder. Inspect the thickness of the brake pads. If necessary, replace them as well. It should be remembered that the pads should be replaced immediately in pairs for each side. All parts should be assembled in the reverse order of dismantling.

How do you know if the front wheel brake cylinders ? Nothing could be simpler! First, you need to lift the wheel with a jack and spin it several times in any direction. If the wheel turns with difficulty and “slows down,” then this is a sure sign of faulty brake cylinders . the brake pads using a large screwdriver or mounting spatula . If the brake cylinders of the front wheels of a VAZ-2101, VAZ-2102, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107 are faulty, then you will be able to separate the pads with great difficulty or not at all. So, it's time to think about what might be needed to replace the front brake cylinders .

And it is recommended to replace them as quickly as possible, since jammed brake cylinders not only worsen the effectiveness of the brakes, but also increase the wear of the front brake pads and reduce the service life of the front hub bearings .

Now, let's get ready to go to a car store or car market. Shopping list: brake cylinders for the front wheels (see photo 1) (two pieces per side - left outer and inner, right outer and inner), clamps and springs (photo 2), it would not be superfluous to buy brake pipes (since old ones are often , “refuse” to unscrew and simply break) and copper sealing washers (under the bolt securing the brake hose to the caliper) (photo 3). Well, and, of course, don’t forget about the bottle... who thought what?)), and I about brake fluid.

Let's move on to the tool that we need to replace the front wheel brake cylinders on a VAZ-2101, VAZ-21011, VAZ-2102, VAZ-2103, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107 : mounting blade, a thin wrench (for knocking out the fingers from the guide brake pads), an awl, a spanner wrench “17”, a socket wrench “14”, pliers, a soft metal hammer (aluminum, bronze or copper), a clamp for the brake hose (photo 4). And also, for unscrewing and installation you may need special wrenches for brake pipes (photo 5).

After serious preparation for work, we move on to the process of replacing the front wheel brake cylinders with:

Loosen the wheel bolts, hang the wheel and remove it. Using a spatula (if it is not available, use a large screwdriver) we spread the brake pads (photo 6). Use pliers to remove the cotter pins (photo 7).

We use a hammer to knock out the guide pins from the eyes of the brake cylinders (photo 8), hold the clamping brackets and remove the pads (in principle, the caliper can be removed with the pads together, but for me, for example, this is more convenient, and the choice is yours). We clamp the brake hose (photo 9).

Using a 14mm socket wrench, unscrew the brake hose (photo 10).

And with a spanner or socket wrench set to “17” we unscrew the two caliper mounting bolts (photos 11 and 12).

We clamp the removed caliper in a vice, unscrew the brake pipe (photo 13) and seat the old clamps (photo 14).

After this, using a simple hammer (you don’t have to spare the old cylinders), we knock the brake cylinders out of their seats (photo 15).

We clean the cylinder seats in the caliper from dirt and rust (photo 16).

We take a new brake cylinder and insert a spring and a retainer into it (photo 17) and, using a “soft” hammer or drift, carefully place the cylinder on the caliper seats (photos 18 and 19).

Install the brake pipe (photo 20).

That's it, the brake cylinders have been replaced . Assembly is carried out in reverse order. Do not forget that when installing the brake hose, it is necessary to replace the old sealing washers with new ones and “bleed” the brakes.

Brake system VAZ 2107

It's no secret that the safety systems provided for the VAZ 2107 have not undergone significant improvements since the first production of the car. There are no airbags or related electronics in such a car. Once you get your hands on such a car, the first thing you need to do is check the brakes. In fact, a car's safety systems are based on the car's braking performance.

Crash test

As crash tests of domestic cars show, it makes no sense to rely on the car body itself. A frontal or side collision with an obstacle already at a speed of 64 km/h will turn the “seven” into an accordion.

Thus, there is no space left for the driver or passengers. Despite all the “unsafety”, the VAZ 2107 is very popular among car owners. Fortunately, it is now not difficult to find spare parts for tuning domestically produced cars and you can modernize your car without any problems.

The device of the "seven" brake mechanism

The system is designed for smooth or emergency stopping. As we have already determined, it is the main security system, and operation of the car is prohibited even if the slightest malfunction is detected.

In a classic braking system, the pedal is mounted on the same axis as the clutch pedal and is equipped with a return spring. This mechanism has a built-in sensor for turning on the rear brake light lamps.

Next comes the brake master cylinder. It is attached to the body in the engine compartment with two bolts and has working braking circuits for the front and rear wheels.

Now you can find vacuum boosters to reduce the effort applied to the pedal. The drive of such an amplifier is a fitting . It is mounted in the intake manifold, connected by a rubberized pipe. For reliability purposes, the front circuit has two fittings per wheel, and the rear circuit has one fitting.

Piston disc brakes are used on the front wheels. They are installed for greater braking efficiency, since a greater load is placed on the front wheels than on the rear ones.

The rear wheels are equipped with drum brakes. Structurally, they are much simpler than disk ones. As is known, their efficiency is extremely low, but is quite sufficient for rear-wheel drive vehicles. In addition, it is not profitable for the manufacturer to install more expensive disk mechanisms. A parking brake mechanism is also built into the rear wheel brakes.

An important mechanism of the system is hidden under the bottom of the car in the rear - this is the pressure drop regulator in the system. This mechanism distributes the pressure that is created during braking between the front and rear circuits.

Removing the brake caliper

To remove the caliper you must do the following:

• lift the car on a lift or jack up the wheel on which the brake caliper needs to be removed;
• Using a wrench, remove the bolt securing the brake hose bracket;

• remove the bracket so that it does not interfere with further actions;

Important: under the bracket fastening bolt there is a spring washer, which must not be lost when dismantling the bolt and bracket.

• unscrew the bolt securing the brake hose;

• remove the bolt after first removing the two o-rings;

• insert a rubber tube or bolt of a suitable diameter into the hole in the brake hose tip to prevent brake fluid from leaking out;
• Use pliers to remove the cotter pins securing the brake pad pins;
• pull out the pins securing the brake pads and remove them using a bit or a thin, but not sharp, screwdriver;

• remove the retaining springs from the brake pads;
• remove the brake pads;

Advice: if you plan to use the brake pads in the future, they should be marked with a marker so that during reassembly they can be installed in the same place where they were. If this is not done, they will wear out faster and brake worse.

• bend the locking plates of the washers on the caliper mounting bolts;

• unscrew and remove the bolts securing the caliper to the steering knuckle;
• Remove the brake mechanism (caliper) of the VAZ 2107 from the brake disc.

Important: the upper and lower caliper mounting bolts differ in the shape of the head. When installing the unit in place, it is necessary not to mix them up.

Basic faults

The brake system itself is quite simple, but some of its elements require special attention. Main types of faults:

• The brake fluid leaks, resulting in a drop in pressure in the system. If a preliminary inspection does not find a leak, it is necessary to check the brake master cylinder. We bend the noise-insulating mat located under the brake pedal and inspect for streaks in the area of ​​the rubber seal of the master cylinder. The presence of drips will indicate that the cause has been found and requires disassembling the cylinder and then replacing the cuff. If there is a vacuum booster, the brake master cylinder must be removed and inspected.
• When you release the brake pedal, the car drives sluggishly. Reason: the rear or front pads are jammed. Seized pads are identified by checking the heat of the corresponding wheel. We touch each disk - the hottest one will be jammed. In the case when these are the front wheels, you can, after removing the wheel, move the brake cylinder. If this fails, you will have to replace it with a new one. In the case of rear pads, the brake wheel cylinder will need to be replaced.
• When you press the pedal, braking does not occur, but it does when you press it several times in a row. This may indicate the presence of air in the system. The solution to the problem is to bleed the brakes to remove air.
• Problem with the handbrake. Most often this problem occurs in winter. It manifests itself in the fact that after a long period of parking, when the handbrake is released, the wheels remain locked. The reason is that the parking brake cable is frozen. During its operation, moisture gets there and freezes in winter. If the casing is severely damaged, it will have to be replaced.

Repair of brake caliper VAZ 2107

A damaged or deformed brake caliper on a VAZ 2107 needs to be replaced. Caliper repair involves replacing faulty brake wheel cylinders. In some cases, instead of replacing the cylinders, they can be repaired.

The procedure for replacing cylinders is as follows:

• clamp the caliper in a vice;
• Unscrew the fittings of the connecting tube with a 10 mm wrench;

• remove the tube connecting the working cylinders;

• Use a hammer to knock out the working cylinders from the guides, after pressing the lock with a screwdriver;
• remove the clamps and replace them with new cylinders (if they are missing); insert the cylinders into the guides;
• install the connecting tube and tighten the fittings.

Repair of working cylinders consists of replacing the rubber sealing rings on the pistons. The order of operations is as follows:

• remove the brake cylinder;
• remove the protective cap from the piston using a screwdriver;
• apply compressed air to the cylinder to push the piston out;
• remove the sealing ring by prying it off with a screwdriver;
• install a new ring;
• lubricate the cylinder, piston and ring with brake fluid;
• insert the piston into the brake cylinder.

Important: before installing new sealing rings and assembling the cylinders, you must make sure that the inner surface of the cylinder and the piston are free of damage, cavities, and deformations. Otherwise, replace the brake cylinder with a new one.

Replacing brake discs yourself

Replacing front discs

Replacing brake discs is necessary when its thickness is less than 9.5-11 millimeters. When the pads wear out, the pistons can come out of their seats and create misalignment. The second reason for replacement may be uneven wear and deep risks .

Such problems increase brake pad wear and reduce braking performance. In these cases, the disks must be replaced. Their timely replacement is the key to your safety.

Remove the wheel and caliper with brake pads. To do this, unscrew the two guide pins.

Next, remove the intermediate ring and the worn disc.

After this, the new disk is installed in the reverse order.

Replacing rear drums

Replacing the rear brake drum is more difficult than the front one, but it is quite doable on your own.

For this replacement, we also remove the wheel and unscrew the two guide pins.

Sometimes the drum gets stuck to the seat. Removing it becomes problematic. When removing, part of the side may break off. To disrupt it, there is the following method: start the engine, then engage first gear and, pressing the brakes, release the clutch. The disk breaks off.

Severe wear of the rubbing surface by the pads also complicates everything. To remove it, take a wooden block and a hammer. Without striking too hard, the drum should come off.

We remove it as soon as it starts to go away.

We inspect the brake drum and if there is serious damage, replace it with a new one.

In conclusion, it should be noted that it is enough to carry out regular checks and timely repairs of the entire brake system and you will not need to worry about the reliability and safety of your car.

The brake system on any car plays an important role, which is the safety of the driver and passengers. In this article, we will look at one of the mechanisms of this system - the front (working) brake cylinder, which provides braking to the front wheels when the brake pedal is pressed.

The product in question, or more precisely, the brake cylinder on a VAZ-2107 car, periodically wears out and becomes inoperative, just like many other parts. A faulty mechanism can cause an emergency on the road, so to prevent this from happening, the performance of this product should be periodically monitored. In this material we will find out where it is located, as well as the features of its replacement for the VAZ-2107 car.

How to bleed brakes on a VAZ 2107

This procedure should be carried out in case of depressurization of the brake system or its damage. It is best to do this in a special pit with the help of two people. You will need a minimum set of tools such as: a bottle, a vinyl tube, and a special wrench of a special structure.

Replacing brake fluid on a VAZ 2107

When bleeding the car, you release air; when replacing brake fluid, you get rid of the remnants of the old one and add new one. The main caveat is that you should not finish the work if the liquid has not become transparent. If you are planning to replace the rear brake columns, you should remember that this work should only be performed in pairs. And of course, you can’t do this without a jack and a wheel wrench. Replacing certain parts of a vase does not require special knowledge, the main thing is to do all the work according to the rules and not to rush.

Front cylinder location

The front brake cylinder is located on the front wheel hubs, next to the wheel rim. Each front wheel has two brake devices, which, when you press the pedal, press the pads against the brake disc on both sides, which ensures effective braking of the car. For clarity, below is a photo in which both devices are indicated by arrows.

After removing the front wheel of the seven, you can see the device data immediately behind it. Having found them, you need to make sure that they are in good working order, or rather, that they are faulty. After all, why change a working part?

When to change cylinders

The main and most common reason for loss of performance, which entails repair or replacement, is jamming of the brake device. If you notice constant braking of the car, a pull to the side when you release the steering wheel when driving in a straight line, or abnormal heating of one of the wheels after driving, perhaps one of the working cylinders has begun to jam. This happens quite often, since aggressive and improper operation, as well as the quality of parts, leads to such consequences. Jamming of the product can occur in any mode of operation - be it constant driving of the car, or its idle time in the parking lot. If at least one of the cylinders on the VAZ-2107 begins to jam, then you should immediately get to the nearest service station and have it repaired. But a service station is expensive, especially for owners of budget cars, so it’s easier to solve the problem yourself, and at home.

Replacement of the product may also be necessary if liquid begins to leak from under the sealing ring. The sealing ring (boot) is shown below in the photo.

If liquid begins to leak from under the rubber band, it means that this will soon lead to a malfunction of the device. You can avoid consequences by responding in a timely manner.

Replacing the front brake cylinder on a VAZ-2107

Replacement begins directly with the removal of the old mechanism. To do this, you need to jack up the front of the car, then unscrew and remove the wheel, and remove the brake caliper. Details of caliper removal can be found in the corresponding section of this website.

Further actions to replace the working mechanism should be carried out as follows:

• The caliper should be placed in a vice, but it is important not to clamp it too tightly. If you squeeze it, then part of the part may simply break off, as a result, replacing the caliper cannot be avoided.
• Once the caliper is removed and clamped in a vice, it is necessary to remove the steel brake pipe. This tube connects both parts of the mechanism. To remove the tube, you need to unscrew two nuts with a wrench. After unscrewing the nuts, you can remove the steel tube. The photo below shows the caliper in a vice, as well as the tube that needs to be removed.
• After this, you need to find a groove on the side in which the spring locking element is located. To remove the brake cylinder, you will need to press this lock with a screwdriver. The photo below shows the location of the groove with a red arrow.

• To remove the working device, you need to hold the spring mechanism with a screwdriver. After pressing the latch, it is necessary to strike the side of the working mechanism with a rubber hammer. You don’t need to hit it too hard, but be sure not to hit the caliper. If you hit the caliper, it may break off. The photo above shows how the working cylinder is struck with a hammer.
• If the product starts to move, then the process is in progress. To dismantle the part in question, you will need to use a long screwdriver or pry bar. The mount should be placed in the resulting hole between the caliper and the cylinder. Below is a photo of how it looks clearly.

• The second cylinder is removed in a similar way. After removing the devices, you can begin to directly replace them with new ones.
• To install a new product in place of a removed one, you must first press a special latch. When pressed, the mechanism must be installed in the guide grooves until this latch is activated.

If the new part will not be inserted into the guide grooves, you can take a file and remove a few millimeters of the metal layer. The main thing is not to overdo it, otherwise the part simply will not be fixed in the caliper.

This completes the replacement of the working cylinder on the VAZ-2107. When installing a new product, pay attention to the presence of a brake bleeder. If it is missing, then you should remove it from the old cylinder and screw it into the new device.

Replacing the brake cylinder of a VAZ 2107

1. Firstly, you need to remove the wheels of your car. Then carefully disassemble the brake caliper. 2. The removed caliper should be clamped as tightly as possible in a vice. If you do not have the opportunity to get a vice, then you can use your own strength and carry out the necessary work on the ground. Of course, this will not be entirely comfortable, but in the absence of conditions this is the most advantageous option. It is worth remembering that you should not use a lot of force in this process; you should clamp it carefully, with an average amount of force. However, this stage of the process will not affect the brake cylinders in any way. You can simply deform this device. 3. For the third stage, a wrench will be useful. Using it, you need to unscrew the 2 nuts between which the connecting tube is installed. This tube should be removed. 4. You should find the groove, which is located in the side of the caliper. Using a screwdriver, you need to get to the lock button, which will help you remove the cylinder. 5. Remove the cylinder carefully using a rubber hammer. If you are planning a replacement, you can spare no effort, but be extremely careful not to hit the caliper, as it can easily become deformed.

Checking the brake system of the VAZ 2107

To check the condition of the brake system, special tools are required. As a rule, at a service station, specialists can easily measure the thickness of the brake disc using a caliper. If you independently test the front brake cylinders on a VAZ 2107, you will need a strong assistant. Pad repair requires some investment. However, to replace it yourself, you need to measure the thickness of the friction linings.
