10.4. Replacement of front brake shoes


Prevention

Surely you 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. Lift a forward part of the car and record on supports. Remove forward wheels.
2. Disconnect the electric socket located on the wire going to the sensor of wear of brake shoes.
3. Press the piston into a support, displacing a support aside, opposite to a piston arrangement.
4. Unscrew a bolt of fastening of the lower directing finger. At the same time for deduction of the directing finger from a provorachivaniye use a thin wrench. For fastening of the directing finger use only a new bolt.
5. Turn a support up on the top directing finger and tie up to a rack with the help of a soft wire.
6. Take two brake shoes from the holder of a support.
7. Measure thickness of an overlay of each brake shoe.
8. If the condition of overlays of brake shoes allows their further operation, clear them, using a pure wire brush and rags.
9. Before installation of blocks check that the directing fingers freely moved in the holder of a support, and be convinced that rubber protective covers of the directing finger are not damaged.
10. Purify dust and dirt from a support and the piston. Check a condition of dustproof consolidation around the piston.
11. If new brake shoes are established, press the piston into a support. It can be made a wooden core or the handle of the hammer. At the same time especially you watch that the piston did not warp also the surfaces of the piston and a boot were not damaged. At a piston vdviganiye brake fluid is forced out from the brake cylinder in a broad tank. Therefore constantly watch liquid level in a tank and if necessary pump out it. At installation of old brake shoes put them on the former places.
12. Insert external and internal brake shoes in the holder of a support.
13. Lower a support on brake shoes, passing a wire from the sensor of wear of a brake shoe through a window in a support. Grease a carving of a bolt of fastening of the directing finger with means against unscrewing (Peugeot recommends Loctite Frenetanch).
14. Press a support that it reached the position, then screw up a bolt of fastening of the directing finger, tightening it the required moment.
15. Connect the electric socket of the sensor of wear of a brake shoe.
16. Check the level of brake fluid in a tank. It should not exceed the marks "max". Several times press a brake pedal in order that blocks nestled on a disk, and repeatedly check the level of brake fluid in a tank.
17. Perform above-mentioned operations on the second forward wheel.
18. Establish wheels and lower the car.
19. Repeatedly check the level of brake fluid.
