Front caliper device for VAZ 2110

Content

Braking of the front wheel is created by a disc type device. The brake discs are permanently attached to the hub.

The mechanism that stops the rotation of the wheel includes:

• caliper VAZ 2110;
• pad guide;
• working cylinder with piston, sealing ring;
• brake pads;
• guide bushings, fingers;
• mounting bolts, washers.

The fixed part is mounted on the steering knuckle and hangs over the working disk. Contains channels into which fingers are inserted. The brake cylinder is bolted to the caliper, creating a caliper, with spring-loaded pads located inside. There are car versions where the VAZ 2110 caliper is equipped with a control indicator, the inner pad contains a wear sensor. The moving part is bolted to the guide pins.

Front caliper design for VAZ 2110: 1 - wheel cylinder; 2 — fitting for bleeding the brake drive; 3 - sealing ring; 4 - piston; 5 — protective cap; 6 — retaining ring; 7 — caliper; 8 — pad guide; 9 — brake pads; 10 — protective cover; 11 — guide pin; 12 — guide pin fastening bolt; 13 — brake hose; 14 — bolt securing the cylinder to the caliper.

The mechanism is hydraulically controlled through a flexible hose connecting the cylinder fitting to a metal pipeline. A protective cover is placed on the finger, preventing contamination of the channels. It is a thin-walled, corrugated rubber tube. It is fixed with the edges by the protrusions of the guide and the finger, compressed and unclenched during operation.

The guides are filled with special lubricant. Brake pad linings undergo wear during operation. The elastic sealing ring automatically adjusts the gap, compensating for abrasion of the linings. An additional bleeder fitting, covered with a boot, is installed on the cylinder body.

Removing the caliper

The mechanism is of a very simple design; dismantling can be done without much difficulty. Even a novice motorist can cope with such work. In order to remove the VAZ-2110 caliper, you will need to perform the following steps:

1. Loosen the wheel bolts on the side being repaired.
2. Raise the side to be repaired using a jack and remove the wheel completely. Install it under the bottom of the car. This will protect you in case the car suddenly falls off the jack.
3. Cars of the tenth family have the caliper attached to the bracket using two M17 bolts. They need to be unscrewed. If you can't strip the threads, use a penetrating lubricant.
4. Unscrew the brake hose, which is located at the top of the caliper.

When dismantling, evaluate the condition of all rubber tubes. If there is damage on them, even small cracks, it is imperative to install new elements. Such breakdowns can lead to the brake system depressurizing while driving.

Possible malfunctions of the front caliper of the VAZ 2110

The VAZ 2110 non-ventilated caliper is used in an aggressive environment and is exposed to temperatures, water, and dust. Contamination, acidification of parts, rupture of casings, and wear of fingers occur. The result is extraneous knocking noises in the device, possible piston jamming, skewed pads, squeaking brakes, and increased braking distance. It is necessary to periodically maintain structural elements, clean surfaces, and add lubricant to the caliper guides. A neglectful attitude will cause an emergency, repairing the VAZ 2110 caliper.

Diagnostics

To check the front brake caliper of the VAZ-2110, you will need to perform the following steps:

1. Assess the condition of the metal piston and the ease of its movement inside the cylinder.
2. Check for metal oxidation, oxide formations or build-ups, or moisture on the elements.
3. Assess the condition of all rubber boots.
4. Check the condition of the VAZ-2110 caliper guides. You must make sure that there is no abrasion, deformation or scuffing on their surface.

Any damage to the caliper body and its and other elements should alert the driver. In this case, it is necessary to change the mechanism.

Preventive Maintenance

At a car company, before the daily departure, a mechanic inspects the car. Few car enthusiasts do the same. Motivation will appear after receiving an answer to the question of how much the front caliper of a VAZ 2110 costs. Online stores indicate prices of 2000 - 2500 rubles without delivery costs. A complete repair kit for the VAZ 2110 front caliper costs three times less. A repair kit for quickly wearing rubber parts costs 140 rubles.

The next forty thousand kilometers on the car’s speedometer is an indicator of mandatory caliper maintenance. You should stock up on time, spare parts, tools, special and universal WD-40 lubricants.

Step-by-step instruction:

1. Place the car on a horizontal surface.
2. Block the rear wheels with special blocks.
3. Loosen the wheel bolts.
4. Raise the front end on a jack. If work is carried out in a garage, provide an insurance support.
5. Unscrew the fasteners and remove the wheel. If there is no support, put it under the front end.
6. Turn the steering wheel towards the VAZ 2110 caliper being repaired for easy access.
7. Release the brake hose from the fork.
8. Bend the corner of the washer.
9. Armed with an open-end or combination wrench, unscrew the upper mounting bolt and loosen the lower one. Use a ratchet wrench.
10. Move caliper 2110 with cylinder to the side.
11. Remove the finger with the protective cover and inspect it. If the protection is destroyed, there are traces of acidification, dirt, liquid - clean and lubricate the channel. Severe contamination, jamming, and wear of the guides lead to the replacement of the pad guide. Security is more expensive.
12. The condition of the channels is satisfactory - remove the old grease. When cleaning rubbing parts, it is not advisable to use degreasing compounds. Use special napkins, soft fabrics soaked in liquid oil.
13. Take a new pin, lubricate it, insert it into the channel, rotate it around the axis, evenly distributing the lubricant. Extract.
14. Put on the cover, assemble the structure, secure the edges of the boot.
15. Prevent lubricant from getting on the disc or pads.
16. Screw on the caliper without fully tightening the bolt.
17. Do the same manipulations with the bottom side.
18. Tighten the fasteners and bend the locking washers.
19. Insert into place and tighten the brake hose fitting.
20. Test the brakes.

Replacing brake pads

1. Follow the first 9 steps of the previous instructions.
2. Open the brake fluid reservoir cap. If the tank is filled under the plug, use a syringe to reduce the level.
3. Inserting a powerful flat-head screwdriver between the pads and the disc, increase the clearances by retracting the piston.
4. Move the moving part to the side.
5. If there is a control sensor, disconnect the connector.
6. Remove the old pads, clean the seats, insert new ones.
7. Check the mobility of the fingers, the condition of the protection, and the disc.
8. Reassemble in reverse order.
9. Operate the brake pedal until the pads adjust the gap.

Replacing the caliper cylinder of a VAZ 2110

1. Carry out preparatory activities in accordance with the eight starting points of the first list.
2. Unscrew, lift up, and temporarily plug the flexible hose.
3. Use a hexagonal L-shaped wrench to loosen the cylinder. Treat rusted fasteners with WD-40.
4. Release the fastening, unscrew the bolts that secure the VAZ 2110 caliper bracket.
5. Disconnect the old cylinder and attach the replacement one.
6. Using a clamp, press the piston.
7. Assemble the mechanism.
8. Connect the hose.
9. Bleed the brakes and check the fluid level.

Modification of the VAZ 2110 caliper

Trying to eliminate the causes of breakdowns and increase the reliability of the braking system, craftsmen make changes to the design. We often hear questions about what to do if the calipers of the VAZ 2110 are knocking. How to change the caliper 2110. How to improve the operation of the mechanism. Similar components of domestic and foreign cars are compared.

The VAZ 2110 is equipped with 13” (inch) discs, type p 13. Brembo produces brake discs p 14”. The VAZ 2110 caliper bracket allows you to use this size in conjunction with pads with a larger lining area made by Fiat. The contact surface increases, the braking distance decreases.

Plastic rings are used on the fingers of foreign cars, reducing knocking in the mechanism. Home craftsmen make transverse grooves and select rubber rings. The modified design is designed to eliminate the beating of the bracket.

It is necessary to take into account the compatibility of the ring material with the lubricant used to prevent jamming. In an effort to improve the design of the braking system, it is logical to use the medical motto - do no harm.
