Removal and installation скобы brakes of back wheels


If bracket brakes 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 has not been tense.

1 Mark a paint position of back wheels concerning a nave. It will allow to establish at assemblage balanced a wheel in its former position. Loosen the 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 hold it in such position. For this purpose it is possible to insert wooden брусок between a seat and a pedal. A seat for this purpose displace back and then again forward. Thus, leakage a brake liquid possibility 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 turn on накидную a nut from connecting муфты, keeping a hose for hexahedron. Otherwise to disconnect a brake hose at a support it is impossible.

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

4 Take out a cable of the gauge of deterioration at the right support. Thus pull for the tip, instead of for a cable.
5 Turn away bolts of fastening directing brakes to a rotary fist накидным a key on 17 mm and remove together with a support and established brake pads from a rotary fist. 1 – caps of bolts of fastening of a support.


6 Establish into place bracket brakes with a support and pads and fix on a rotary fist.
7 Tighten fastening bolts скобы the moment 65 Nm.
8 Join a socket of the gauge of deterioration brake Pad 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 marks put at removal have coincided. Preliminary grease with a thin layer bearing greasings 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 100 Nm.

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

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

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

The brake liquid should not pour out or be thrown out with a household waste at all. Local authorities inform drivers on places of its possible recycling.
