Replacement of blocks of disk brake mechanisms

Replacement of blocks should be made at the same time on brake mechanisms of both lobbies (or back) wheels - never change blocks only one of brake mechanisms. Besides, it is necessary to pay attention that the dust developed by brake mechanisms in the course of their work can contain unhealthy asbestos. At all do not blow off a dust from surfaces of components of brake mechanisms the compressed air and do not inhale it. Works are best of all for making in a protective respiratory mask. At all do not use for cleaning of components of brake mechanisms solvents on an oil basis or gasolines - use only patent means for cleaning of brakes!

Procedure is applicable for replacement of blocks both forward, and back disk brake mechanisms.


  1. Uncover the tank of brake liquid.
  2. Weaken nuts of fastening of forward wheels, поддомкратьте a front of the car and establish it on props.
  3. Remove forward wheels. Work with each of brake mechanisms serially, the second keeping as a model of assembly in case of doubts in correctness of the idea of it.
  4. Carefully check a condition of a brake disk (The section condition Check, removal and installation of a brake disk). If there is a need for carrying out stanochny processing, remove a disk (cm lower in this Section). At the same time there is also a possibility of extraction of blocks from a support.
  5. Push the support piston into the cylinder, having provided free space for installation of new blocks (which thickness more than at worn-out old). For performance of this task it is possible to use a clamp. At a piston otzhimaniye liquid level in the main brake cylinder will automatically rise. Watch that it did not start to follow too much, in case of need suck away surplus (a syringe or an enema - at all a mouth!).
  1. By means of a big clamp push the piston into the support cylinder - notice that one of sponges of a clamp rests against the plane on the back party of a support, and second (mobile) - in an external block.
  1. Carry out procedure of change of blocks, being verified with illustrations below. Strictly observe an operations procedure and attentively get acquainted with contents of explanations to pictures.
  1. Before removal of a support remove all traces of a brake dust by means of a patent cleaner.
  1. For removal of a support remove two fixing pins (the top and bottom arrows); do not give a hollow bolt (the central arrow) fastening to a support of a brake hose if are not going to make major maintenance of a support.
  1. Remove a support; now it will be a high time to check on existence of traces of leakages of liquid of a surface round a piston boot, existence of leaks speaks about need of carrying out major maintenance of a support (The section Removal, major maintenance and installation of a support of the disk brake mechanism).
  1. If no works with a support are carried out, tie up it aside a piece of a wire to a suspension bracket element - watch that the brake hose did not stretch!
  1. For extraction of an external block from a support of the brake mechanism of a forward wheel wring out up ears from each of the block parties, release clips of fastening of a block to a support and remove a block.
  1. For extraction from a support of an internal block take its clamp from a cavity in a piston body.
  1. Take plugs of both fixing pins and examine them on existence of traces of corrosion and wear; if any of pins it is damaged, replace it.
  1. If the boot of a pin or the plug bursts, is torn or overdried, replace it.
  1. Grease plugs with high-temperature greasing.
  1. Establish plugs into place.
  1. Before installation of new brake shoes wring out the piston in the nest in a support against the stop, having provided with that sufficient free space for clothing of new blocks (bigger than worn-out thickness) on a disk.
  1. Enter a clamp of an internal block into a cavity in a piston body; make sure that the clamp was reliably latched in the piston (a block should nestle densely on the piston).
  1. Establish a new external block, having firmly pressed its ears thumbs, as is shown in a picture; Make sure that the block correctly was fixed in clips.
  1. Establish support assembly with blocks on a disk, insert fixing pins and tighten them with demanded effort.
  1. At support installation into place tighten pins of its fastening with demanded effort. On termination of works several times strongly squeeze out a brake pedal for a usadka of new blocks on a disk.
  2. Before starting car operation, check brake system on existence of leaks and make sure of serviceability of functioning of brakes.
