Removal and installation directing a forward brake

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.


 REMOVAL

1 Mark paint the provision of the corresponding forward wheel concerning a nave. It will allow to establish at assembly an otbalansirovanny wheel in its former situation. Weaken 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 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 the pipeline from the connecting coupling (an arrow on an illustration), differently it is impossible to disconnect a brake hose at a support.

A quantity of brake liquid can flow out. Bring together her in a bottle which should be intended only for brake liquid.

4 Rasstykuytes I will corrode a wear signaling device at the left support-1-. Thus do not pull for a cable.

5 Turn out bolts of fastening of-1-brackets of a brake and remove a bracket with a support and the inserted brake shoes.


 INSTALLATION

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

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

3 Fix a brake bracket slightly greased bolts the moment of 110 N • m.
4 Join the socket of the sensor of wear on the left side of the car at a brake shoe. 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 a cap nut. Thus watch, that the hose was not overwound. Check freedom of a course of a hose at a full turn of a steering wheel.
6 Remove air from brake system, address to the Section air Removal from brake system.
7 Establish into place forward 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 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 of 100 N • m.
8 Turn a steering wheel to the right and on the left against the stop and check, whether the brake hose follows all movements of a wheel at the car standing on wheels.

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

9 Check level of brake liquid in the tank, if necessary add 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 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.
