11.3. Removal and installation of a forward support



1. Mark with paint the provision of forward wheels concerning naves. It will allow to establish at assembly the balanced wheels in their former situation. Weaken bolts of fastening of a wheel before a car poddomkrachivaniye. Lift a forward part of the car, put it on supports and remove forward wheels.

Lifting operation and installations of the car on supports is connected with danger! Therefore before carrying out operation study Poddomkrachivaniye's Section and towage of Introduction to the management.

If the support is removed only for removal of brake shoes or a brake disk, it is not necessary to turn out the brake pipeline from a support. In this case fix a support by a wire to a suspension bracket so that the hose was not overwound and was not exposed to stretching.

2. Turn out a brake hose from a support as it is described in the Section Removal and installation of a brake hose.

At a vskryvaniye of a brake contour brake fluid follows. Merge it in a bottle which has to be intended only for these purposes. It is previously possible to suck away liquid from the tank by means of the special device. Observe security measures concerning brake fluid, address the Section Removal of Air from the brake system.

3. Right brake: Take out the wear sensor plug from the socket (1). At the same time do not pull for a cable. Turn out the screw (2) and remove the socket (1) from a support.

4. Remove brake shoes, address appropriate section.

If the support is established again, it is necessary to watch that the piston did not go out of the cylinder.

5. Turn out bolts (4) above and below and remove a guide of blocks (5) from a rotary fist.

Big moment of an otvorachivaniye! Make sure that the car is reliably fixed on supports and the wrench is horizontal. The specified bolts can be turned off when the car costs on wheels.



1. Establish a guide of blocks and fix by two new self-stopped bolts the moment 115 Nanometers.

Big moment of an inhaling! Make sure that the car is reliably fixed on supports and the dynamometer key costs horizontally. Bolts can be tightened finally when the car costs on wheels.

2. Establish brake shoes, address appropriate section.

Do not allow hit on frictional surfaces of a brake disk and blocks of lubricant or oil.

3. Right brake: Join the wear sensor socket on a support. Enter the sensor plug into the socket.
4. Establish a brake hose, address appropriate section.

The brake hose should not be twisted.

5. Remove air from the brake system, address appropriate section.
6. Establish into place a forward wheel so that the marks put at removal coincided. Previously grease with a thin layer of bearing lubricant the aligning wheel disk belt on a nave. Do not grease bolts of fastening of wheels. Replace rusty bolts. Wrap bolts.

Check that at the maximum angle of rotation of a steering wheel the brake hose did not concern a wheel.

7. Lower the car on wheels and tighten bolts cross-wise the moment of 110 Nanometers.

Several times, strongly press a brake pedal until notable resistance is felt. Thus brake shoes adjoin to a disk and hold the working position.

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

Carry out reliability control:

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