Removal and installation of a bracket of a brake of back wheels


If the bracket of a brake and a support are disconnected only for removal of a brake disk, it is not necessary to disconnect a brake hose. Otherwise after installation it is necessary to delete air from brake system. Suspend a support on a wire to a suspension bracket so that the hose was not braided and was not tense.

1 Mark paint the provision of back wheels concerning a nave. It will allow to establish at assembly an otbalansirovanny wheel in its former situation. Weaken bolts of fastening of wheels at the car standing on the earth. Lift a back part of the car, put it on supports and remove back wheels.
2 Slightly press a pedal of a brake and keep it in such situation. For this purpose it is possible to insert wooden whetstone between a seat and a pedal. A seat for this purpose displace back and then again forward. Thus, possibility of an effluence of brake liquid is excluded from the tank after a detachment of hoses and hit in air system.
3 Disconnect a brake hose in a junction with the pipeline. For this purpose unscrew a cap nut from the connecting coupling, holding a hose for a shestigrannik. Otherwise to disconnect a brake hose at a support it is impossible.

Thus a quantity of brake liquid can flow out. Collect following liquid in the capacity intended only for this purpose.

4 Take out a cable of the sensor of wear at the right support. Thus pull for the tip, instead of for a cable.
5 Unscrew bolts of fastening directing brakes to a rotary fist a cap key on 17 mm and remove together with a support and the established brake shoes from a rotary fist. 1–caps of bolts of fastening of a support.


6 Establish into place a brake bracket with a support and blocks and fix on a rotary fist.
7 Tighten bolts of fastening of a bracket the moment of 65 N • m.
8 Join the socket of the sensor of wear of brake shoes on the right side of the car.
9 If the brake hose was disconnected from a support, connect it at first to a support, and then with the brake pipeline.
10 Establish into place back wheels so that the markings put at removal coincided. Previously grease with a thin layer of bearing greasing a seat of a disk of a wheel on a nave. Bolts of fastening of wheels do not grease. Rusty bolts replace with the new. Fix wheels bolts. Lower the car on wheels and tighten fastening bolts cross-wise the moment of 100 N • m.

Several times strongly press a brake pedal in a standing position so that to feel resistance. Thus, blocks occupy the working situation at a brake disk.

11 Check liquid level in the tank, if necessary add liquids to MAX mark.

— Whether brake hoses are fixed?
— Whether the brake hose in the holder is fixed?
— Whether unions for air removal are tightened?
— Whether enough of brake liquid is filled in?
— On the working engine check tightness. For this purpose press a brake pedal effort of 200-300 N (20-30 kg) during 10 pages. The pedal should not weaken. Check all accessions on tightness.

Brake liquid should not pour out or jump out with a household waste at all. Local authorities inform drivers on places of its possible utilization.
