Removal, dismantling, check, assemblage and installation of supports of brake mechanisms

Components of assemblage of the brake mechanism of a forward wheel are presented on an illustration Assemblage of the forward brake mechanism.

Assemblage of the back brake mechanism

1 — the Lining
2 — the Stopper
3 — the prorolling Union
4 — the Support
5 — Pylnik
6 — the Piston
7 — the Ring of a cover of the piston
8 — a piston Cover

9 — piston Consolidation
10 — the Directing plug
11 — the Main hairpin
12 — Skoba of a support
13 — External brake колодка
14 — Internal антивизговая an overlay
15 — Antivizgovaja an overlay
16 — Holders brake pads
17 — Internal brake колодка

Removal and dismantling


  1. Remove a corresponding wheel and temporarily fix a brake disk wheel nuts.
  2. Turn out from a support a bolt, remove a lining and disconnect a flexible brake hose from a support.

Prepare capacity for gathering of a brake liquid.

  1. Turn out adjusting bolts of a support (on the back brake mechanism – one bolt) and remove a support with brackets.
  2. Remove brake pads with антивизговыми overlays and holders pads.
  3. On the back brake mechanism remove, the main hairpin directing the plug with two epiploons and a cover of the main hairpin.
  4. By means of a screw-driver remove a ring of a cover of the brake piston and a cover.
  5. Lay between the piston and a support rags not to damage the piston at its extraction and, having submitted compressed air to the union of the brake mechanism, push out the piston from the cylinder.

Do not hold fingers between the piston and a support during removal of the piston by means of compressed air.

  1. Screw-driver remove piston consolidation:
    • On the forward brake mechanism;
    • Remove with brackets a support two directing pins;
    • Remove directing plug from the top party of a directing pin;
    • Bring down two duster by means of a screw-driver and a hammer.



  1. Measure a thickness of brake disks and overlays brake pads and compare the received values to requirements of Specifications of the Head Brake system. Examine pads and disks on presence of mechanical damages. If necessary replace pads and-or disks.
  2. Measure axial palpation of a disk on distance of 10 mm from its external edge and compare result of measurement to requirements of Specifications of the Head Brake system. If necessary check up axial люфт the bearing. Adjust disk palpation for what execute following operations:
    • Turn out two bolts of fastening brackets a support to a rotary fist and remove bracket;
    • Remove a brake disk and establish it in the position turned from original on 1/5 turns;
    • Tighten wheel nuts with effort of 103 Nanometers;
    • Measure disk palpation in this position and write down results of measurement;
    • Repeat last three operations for the remained three positions of a disk on a nave;
    • If in any of positions disk palpation meets requirements of Specifications of the Head Brake system, establish a disk in this position. Otherwise replace a disk and again measure its axial palpation;
    • Establish bracket a support and tighten bolts of its fastening with demanded effort.

Assemblage and installation


  1. Assemblage and installation are made upside-down. Pay attention to following moments:
    • Do not suppose hit of oil and greasing on frictional overlays brake pads;
    • At installation dusterов track, that their metal parts reliably adjoined to скобе a support;
    • Tighten all connections with demanded efforts;
    • After installation fill brake system with a liquid, pump over it and check up system on leaks.
