Repair of the wheel brake cylinder

If the wheel cylinder is not required to be replaced, it can be sorted in the established state. Previously it is necessary to remove brake shoes. The wheel brake cylinder the latest should be replaced when brake fluid gets through cuffs. When replacing brake shoes it is always necessary to remove from the cylinder boots and to look in the cylinder. If behind boots it is damp or all wheel cylinder is covered with brake fluid, to replace the cylinder. Besides replacement is necessary if pistons in the cylinder slide hardly, there are grooves or a rust. In one of these cases the wheel either does not slow down, or is braked constantly.

1 — boots
2 — pistons
3 — cuffs of pistons
4 — caps

5 — a spring
6 — a rubber cap
7 — the pumping gate
8 — a steel ball

Removal

 PERFORMANCE ORDER

  1. To remove brake shoes.
  2. To remove boots the screw-driver. Carefully, not to damage caps.
  3. To take out both pistons with cuffs.

At the same time can flow out a little brake fluid, enclose a rag. To take out a spring.

  1. To remove cuffs from pistons, at the same time not to damage pistons.
