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.

4. Remove the sealing ring pos. 8 and support cup pos. 7 with crackers pos. 5 and spring pos. 6 from the screw.
5. The thrust ring pos. is disconnected. 4 and a stop screw.

After disassembling the unit, the parts are checked for faults:

1. The working surfaces of the pistons, cylinder and thrust rings must be smooth, without scratches or roughness. Otherwise, fluid leakage and premature wear of pistons and seals may occur.
2. Defects on the mirror surface can be eliminated by grinding or lapping.

Tip: Care must be taken not to increase the internal diameter of the cylinder.

1. The thrust screw, springs, support cup and crackers are visually checked. If they are damaged, parts are replaced.
2. Seals pos. 8 are replaced with new ones.
3. If necessary, change the protective caps pos. 10.
4. The structure is assembled in the reverse order.

In this case, you need to take into account:

1. All parts are generously lubricated with brake fluid.
2. The thrust screws must be tightened to a torque of 3.9 – 6.9 Nm.
3. The slot located on the thrust rings is directed vertically upward, the deviation should not be more than 30 degrees. This ensures that all air is removed from the drive mechanism when bleeding the brake.
4. Using the device, the pistons are pressed into the cylinder body.
5. After assembly, the movement in the housing of each piston is checked, which should be from 1.25 millimeters to 1.65 millimeters.
6. Protective caps are installed.
7. Timely repair or replacement of rear brake cylinders is a guarantee of road safety.

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.
