12.3. Replacement of front brake shoes

GENERAL INFORMATION

Two types of lobbies brake a support are applied:

  – models with continuous forward disks – Bendix supports;
  – models with the ventilated forward disks – Girfing supports.

Prevention

It is obligatory to make replacement of all blocks on one axis of the car even if the limit of wear was reached by one block. If blocks are repeatedly established, before removal they need to be marked.

During the work of brake shoes brake dust which contains asbestos, unhealthy is formed. Therefore when cleaning brake shoes do not use compressed air and do not inhale dust.


PERFORMANCE ORDER
1. To lift a forward part of the car and to record on supports.
2. To remove forward wheels.
3. To disconnect the electric socket located on the wire going to the sensor of wear of brake shoes.
4. To press the piston into a support, displacing a support aside, opposite piston arrangements.
Bendix support

Prevention

At installation of blocks it is necessary to use a new collar of fixing of a plate of fastening of brake shoes.


5. Using flat-nose pliers, to remove a small collar of fixing of a plate of fastening of brake shoes.
6. To take a plate of fastening of blocks from a support.
7. To take brake shoes from a support, noting an arrangement of a spring of anti-jingle and to remove a spring from a block.
8. To measure thickness of an overlay of each brake shoe.
9. If the condition of overlays of brake shoes allows their further operation, to clear them, using a pure wire brush and rags.
10. Before installation of blocks to check that the directing fingers freely moved in the holder of a support and to check that rubber protective covers of the directing finger are not damaged.
11. To purify dust and dirt from a support and the piston.
12. To check a condition of dustproof consolidation around the piston.
13. If new brake shoes are established, to press the piston into a support. It can be made a wooden core or the handle of the hammer. At the same time especially to watch that the piston did not warp also the surfaces of the piston and a boot were not damaged.
14. At a piston vdviganiye brake fluid is forced out from the brake cylinder in a broad tank. Therefore constantly to watch liquid level in a tank and if necessary to pump out it.
15. At installation of old brake shoes to put them on the former places.
16. To establish the spring preventing a tinkling sound of brake shoes.
17. To establish brake shoes in a support.
18. At the correct installation of brake shoes if to look at blocks from a forward part of the car, the flute on an internal block has to be above, than a flute on an external block (B – flutes on brake shoes, D – a spring collar, V – the pumping union).
19. To establish a plate of fixing of brake shoes and to record it a spring collar.
20. To connect the socket of the sensor of wear of brake shoes.
21. To check the level of brake fluid in a tank. It should not exceed the marks "max".
22. Several times to press a brake pedal in order that blocks nestled on a disk and repeatedly to check the level of brake fluid in a tank.
23. To perform the same operations on the second forward wheel.
24. To establish wheels and to lower the car.
25. To repeatedly check the level of brake fluid.
Girling support

Prevention

At installation of brake shoes it is necessary to use a new bolt of fastening of the directing finger.


26. To unscrew a bolt of fastening of the lower directing finger. At the same time for deduction of the directing finger from a provorachivaniye to use a thin wrench. For fastening of the directing finger to use only a new bolt.
27. To turn a support up on the top directing finger and to tie up to a rack with the help of a soft wire.
28. To take brake shoes from the holder of a support.
29. To measure thickness of an overlay of each brake shoe.
30. If the condition of overlays of brake shoes allows their further operation, to clear them, using a pure wire brush and rags.
31. Before installation of blocks to check that the directing fingers freely moved in the holder of a support and to check that rubber protective covers of the directing finger are not damaged.
32. To purify dust and dirt from a support and the piston.
33. To check a condition of dustproof consolidation around the piston.
34. If new brake shoes are established, to press the piston into a support. It can be made a wooden core or the handle of the hammer. At the same time especially to watch that the piston did not warp also the surfaces of the piston and a boot were not damaged.
35. At a piston vdviganiye brake fluid is forced out from the brake cylinder in a broad tank. Therefore constantly to watch liquid level in a tank and if necessary to pump out it.
36. At installation of old brake shoes to put them on the former places.
37. To insert external and internal brake shoes in the holder of a support.
38. To lower a support on brake shoes, passing a wire from the sensor of wear of a brake shoe through a window in a support.
39. To grease a carving of a bolt of fastening of the directing finger with means against unscrewing (Peugeot recommends Loctite Frenetanch).
40. To press a support that it reached the position, then to screw up a bolt of fastening of the directing finger, tightening it the required moment.
41. To connect the electric socket of the sensor of wear of a brake shoe.
42. To check the level of brake fluid in a tank. It should not exceed the marks "max".
43. Several times to press a brake pedal in order that blocks nestled on a disk and repeatedly to check the level of brake fluid in a tank.
44. To perform the same operations on the second forward wheel.
45. To establish wheels and to lower the car.
46. To repeatedly check the level of brake fluid.
