Removal and installation directing forward brakes

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.


 REMOVAL

1 Mark a paint position of a corresponding forward wheel concerning a nave. It will allow to establish at assemblage balanced a wheel in its former position. Loosen the bolts of fastening of a wheel at the car standing on the earth. Lift a forward part of the car, put it on supports and remove a forward wheel.
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 the pipeline from connecting муфты (arrows on an illustration), differently it is impossible to disconnect a brake hose at a support.

A quantity of a brake liquid can flow out. Collect it in a bottle which should be intended only for a brake liquid.

4 Rasstykujte a socket of a signalling device of deterioration at the left support-1. Thus do not pull for a cable.

5 Turn out bolts of fastening-1 скобы brakes and remove bracket with a support and inserted brake pads.


 INSTALLATION

1 Measure a thickness of a brake disk, address to Section Measurement of a thickness of a brake disk.
2 Put into place bracket brakes with a support and inserted pads.

If the brake hose is attached, watch that it has not been overwound or tense. Check up freedom of moving of a brake hose at a full rearrangement of a steering wheel.

3 Fix bracket brakes slightly greased bolts the moment 110 Nm.
4 Join a socket of the gauge of deterioration on the left side of the car at brake pads. The wire should pass in a loop of a cover of the union of removal of air
5 Establish car wheels directly. Establish a brake hose at the holder of connection and fix a hose накидной a nut. Thus watch, that the hose was not overwound. Check up freedom of a course of a hose at a full rerun of a steering wheel.
6 Remove air from brake system, address to Section Removal of air from brake system.
7 Establish into place forward 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 a wheel 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.
8 Turn a steering wheel to the right and on the left against the stop and check up, whether the brake hose follows all movements of a wheel at the car standing on wheels.

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

9 Check up level of a brake liquid in the tank, if necessary add a liquid to a mark the MOVE.

— 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.
