12.15. To make suitable a support and the piston of the brake mechanism – replacement of protective cuffsIn the presence of the defective or carelessly mounted protective cuffs the dirt and a moisture will get into the hydraulic cylinder. Eventually sliding pistons then begin slowly, but confidently to rust. Consequences: high degree of deterioration of brake overlays and disks, non-uniform brake action.

Dismantle or mount brake overlays as it is described above and...
... In the beginning check up a free wheeling of overlays in mines. If necessary clean mines a rigid wire brush or average шлицевой a screw-driver and blow compressed air. Track to damaging protective cuffs or to weaken their landing. Before again establishing brake overlays, grease all contact surfaces with heat resisting copper paste.
Needless to say, supports also should have a free wheeling. If is not present, clean and grease sliding surfaces as it is told above, heat resisting copper paste.

Check of the piston of the brake cylinder
|
|
Before checking pistons on "passableness", establish as an emphasis a clamp with wooden бруском on a support. It will protect the piston from damages – it cannot slip out more the cylinder any more. The opposite support, naturally, should be completely mounted.
Ask the assistant to press a brake pedal cautiously now. If the piston is clamped, the assistant "pumps over" a brake pedal until it will not seem outside. In advance put монтировочный the lever between the piston and a disk. As soon as there will be a piston, send it back in the cylinder by means of the lever. Repeat this procedure until the piston it will not be easy to slide in the cylinder.

Attention: if these actions in what have not resulted the support for repair in a workshop is better to send. |

Replacement of a protective cuff
|
|
Wring out an old cuff the bent welded wire or the small bent screw-driver from a brake support and the piston. Thus try not to scratch a piston or cylinder surface. Track, whether the brake liquid follows from the cylinder. In this situation it is better to send a support «on treatment» in a workshop.
Clean condensing surfaces денатурированным spirit or a pure brake liquid. Before installation of new cuffs preserve the cleared surfaces paste for brake cylinders (Ate, Bosch, Girliling).
Press cautiously new cuff to condensing surfaces, track that cuffs sat densely and only after that...
... Press against the stop the piston back into the cylinder.
Establish brake overlays as it is described above. Check up level of a brake liquid in a compensatory tank.
Before putting the car on wheels, check up all brake system on tightness. And only after that finish installation in return sequence.
