9.9.2. Replacement of blocks of brake mechanisms of back wheels

Minimum admissible thickness of frictional overlays of brake shoes makes 0,5 mm.
Replace blocks in the following cases:
– thickness of frictional slips less admissible value;
– the surface of slips is greasy;
– the frictional slip is unsteadily connected to the basis;
– slips with deep furrows and chips.
It be required to you: a key for bolts of wheels, пассатижи or a screw-driver with a flat edge, sliding пассатижи.
1. Include the I transfer and establish an emphasis under forward wheels.
2. Check, that the lever of the parking brake was lowered against the stop down (the car is stirred up).
3. Remove a back wheel.
4. If level of brake liquid is in a tank of the main brake cylinder on a label of "MAX" or comes nearer to it, pump out a part of liquid from a tank. Otherwise at replacement of blocks it can be splashed out.
6. Unhook пассатижами from a forward block the unbent end of the bottom coupling spring...
7.... also remove a spring.

Good advice
For convenience of removal of the bottom coupling spring deduce the bottom ends of brake shoes from an emphasis.

8. Unhook пассатижами from a rasporny level the unbent end of a fixing spring...

Prevention
At work пассатижами or a screw-driver be careful. We recommend to use special pincers for removal of coupling springs.

9.... and, having turned the second end of a spring in an opening of a back block, remove a spring.
10. Holding a basic rack, press a cup of fastening of a clamping spring, turn it on a turn quarter...
11.... also remove a cup and a spring, and also a basic rack.
12. Similarly remove a cup with a clamping spring of a forward block...
13.... also remove a forward block assembled with a rasporny level, a coupling spring, an adjusting wedge and its spring.
14. Disconnect a cable tip from the razzhimny lever and remove a back brake shoe.
15. Remove a spring of adjustment of gaps.
16. Unhook пассатижами from a rasporny level the end of the top coupling spring...
17.... and, having turned the second end of a spring in an opening of a back block, remove a spring.
18. Remove a rasporny level...
19.... and adjusting wedge of gaps.

Prevention
Right after removal of blocks fix pistons of the working cylinder in any available way (for example, pull together with a rubber plait or connect a wire), differently pistons can be вытолкнуты from the cylinder a rasporny spring and from hydrosystem brake liquid will flow out.


Fig. 9.3. Details of the brake mechanism of a back wheel (details of the brake mechanism on the left side are shown): 1–cups of clamping springs; 2–clamping springs; 3–basic racks; 4–adjusting wedge of gaps; 5–rasporny level; 6–coupling spring; 7–a fixing spring; 8–back block; 9–Razzhimny lever of the parking brake; 10-bottom coupling spring; 11-spring of adjustment of gaps; 12-forward block

20. Clear of pollution and examine details of the brake mechanism (fig. 9.3). Deformed or strongly korrodirovanny details replace. Lost elasticity and the bent springs replace.


Good advice
At each dismantling of the brake mechanism replace new clamping springs, cups of springs and basic racks.

21. Put on places of a friction of brake shoes about a brake board refractory greasing for brake mechanisms.
22. Release pistons of the working cylinder from the fixing adaptation, compress sliding пассатижами pistons of the working cylinder and establish brake shoes as it should be, the return to removal.
23. A screw-driver raise up an adjusting wedge of gaps for data of blocks and establish a brake drum and a wheel into place.
24. Adjust a gap between brake shoes and a drum, having pressed 10–15 times a brake pedal.
25. Similarly replace brake shoes of the brake mechanism of other wheel.
26. After installation of brake shoes adjust lay brake system (see. «Adjustment of a drive of the parking brake»).
