8.5. Replacement of forward brake shoes



Surely make replacement of all blocks on one axis of the car even if the limit of wear were reached by one block. If blocks are repeatedly established, before removal they are necessary for marking.

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

1. Lift a forward part of the car and fix on supports. Remove forward wheels.
2. Disconnect the electric socket from the sensor of wear of brake shoes.
3. From the outer side of a support remove fixing spring.
4. Remove dustproof caps from the internal ends of directing bolts.
5. Unscrew directing bolts of a support.
6. Lift a support with an internal block.
7. Using a soft wire, tie up it to a forward rack.
8. Remove an internal block from the support piston.
9. Remove an external block from the holder of a support.
10. Clear a dust and dirt from a support, and a rust from edge of a brake disk.
11. Measure thickness of brake shoes.
12. If blocks are suitable for further operation, clear them, using a wire brush or rags.
13. Before installation of blocks check that directing bolts easily move in a support.
14. If new brake shoes are established, press the piston into a support a wooden core or the hammer handle. Thus watch, that the piston did not warp also surfaces of the piston and a boot were not damaged. At a piston vdviganiye brake liquid is forced out from the brake cylinder in a broad tank. Therefore constantly watch liquid level in a tank, and if necessary, pump out from a tank its small amount.
15. Check that dredging on the piston of a support is established, as is shown in drawing. If necessary turn the piston in the correct situation.
16. Establish an internal block on a support. Thus the spring bracket should be established in piston dredging.
17. Establish an external brake shoe.
18. Establish a support with an internal block on the holder of a support.
19. Screw in directing bolts of a support and tighten them the demanded moment.
20. Establish dustproof caps on directing bolts of a support.
21. Establish fixing spring on a support. Thus the ends of a spring should settle down in a support opening.
22. Connect the sensor of wear of brake shoes.
23. Several times press a brake pedal that brake shoes nestled on a brake disk. Check level of brake liquid in a tank.
24. Repeat above-mentioned actions on the second wheel.
25. Establish wheels and lower the car.
26. Check level of brake liquid.
