Replacement of brake shoes

The description of check of brake shoes is provided in the Section the General checks of the brake system.

Assembly of the forward brake mechanism

1 — the pumping Union
2 — the Support
3 — Laying
4 — the Directing pin
5 — the Piston
6 — Consolidation of the piston
7 — a piston Cover
8 — a piston cover Ring
9 — the Directing plug

10 — the Boot
11 — the Brake disk
12 — a support Bracket
13 — Holders of brake shoes
14 — the Indicator plate of wear of blocks
15 — Antivizgovaya a slip
16 — the Internal antivizgovy slip
17 — the Internal brake shoe
18 — the External brake shoe


  1. Assembly of the brake mechanism of a back wheel is given in the illustration Assembly of the Back Brake Mechanism.
  2. Remove the corresponding wheel and temporarily fix a brake disk by wheel nuts.
  3. Turn out a bolt of fastening of a support, cast away a support and reliably tie up it.

Do not disconnect flexible hoses from a support.

  1. Remove 2 brake shoes with four antivizgovy overlays and an indicator plate of wear of blocks.
  2. Remove 2 holders of brake shoes.

Not deformed holders it is possible to reuse.

  1. Check a condition of a brake disk (see the Section the General checks of the brake system).
  2. Installation is made as it should be, the return to an order of dismantle of components. Turn removal on the following remarks:
    • At installation of new blocks establish as well new antivizgovy slips;
    • Grease both parties of internal antivizgovy slips with special lubricant for brakes;
    • Do not allow hit of oil and lubricant on frictional overlays of brake shoes;
    • At installation of a support wring out the piston, for example, the hammer handle if the piston goes hardly, weaken the pumping union to allow to flow out brake fluid;
    • Delay all connections with the required efforts.
