9.4. Replacement of blocks of disk brake mechanisms of forward wheels

Design of disk brake mechanisms of forward wheels



  1. Car front also establish to Poddomkratta it on props (see the illustration Scheme of an Institution of Props for fixing of the car in the lifted situation). Remove the corresponding forward wheel. Turn out the lower fixing bolt and develop a support up on the directing finger.
  2. Remove holders of blocks and adjusting laying. Remove blocks and measure the residual thickness of their frictional slips (the minimum admissible value makes 2.0 mm). In case of need make replacement of blocks.



  1. Wipe a boot of the piston of the wheel cylinder and the directing fingers.
  2. Wring out the piston and put an internal block in an anchor bracket.
  3. Grease the support surfaces contacting to holders of blocks with special brake lubricant, then establish an external block and adjusting laying.
  4. Establish holders of blocks.
  5. Lower a support in regular situation and establish the lower fixing bolt.
  6. Tighten bolts with the required effort, then several times squeeze out a pedal of a foot brake for shrinkage of components of the brake mechanism.
