Removal and installation of front brake shoes



  1. To mark the provision of a disk of a wheel concerning a nave that the balanced wheel could be established in former situation.
  2. To weaken nuts of a wheel of the car standing on the earth.
  3. To lift a forward part of the car.
  4. To remove a wheel.

Change by places of blocks of the right and left wheels is inadmissible. Change by places can lead to uneven brake influence. It is obligatory to replace at the same time all blocks of one axis even if the limit of wear was reached by only one block. If blocks are established again, before removal they should be marked.

  1. Cars from 10/89 g of the issue, except the station wagon models: To slightly screw 2 nuts of a wheel to stop a brake disk.
  2. To delay a brake support a hand outside and it to press the piston.

Cars to 9/89 g of the issue and "station wagon"


  1. To remove separate elements as numbering. At first to beat out fastening pins-1 hammer and a punch outside. Instead of a drift it is possible to use a nail.

Cars from 10/89 g of the issue, except the station wagon model


  1. To remove separate elements as numbering. At first to take out the screw-driver of a spring of fastening-1-and-2-, considering at the same time adjusting situation. Then to beat out pins of fastening-3-by means of the hammer and a drift or nailing.

To replace slabosidyashchy pins of fastening.

  1. To take out brake shoes and intermediate (protivoskripny) plates by means of nippers, the screw-driver or a shock stripper. If blocks rusted, the special stripper is necessary (for example, HAZET).


At the removed brake shoes not to press a brake pedal, otherwise the piston will be squeezed out from the case.


  1. To clear the directing surfaces and places of landing of blocks in the mine of the case a suitable soft metal brush or to wipe with a rag with alcohol. Not to apply the solvents or tools containing mineral oils with keen edges.
  2. Before installation of blocks it is necessary to check a brake disk for existence of grooves, having felt it fingers. Brake disks with grooves should be replaced.
  3. To measure thickness of a brake disk.
  4. To check for existence of cracks a boot and protective cuffs in a support. It is obligatory to replace the damaged cap as the getting dirt quickly will result in leakage of a support. For this purpose the brake support has to be removed and sorted (it is carried out in a workshop).
  1. To press the brake piston special adaptation. It can be done and a strong wooden core (the hammer handle), at the same time especially to watch that it did not warp, both the surfaces of the piston and a boot were not damaged.

At a piston vdviganiye brake fluid is forced out from the brake cylinder in a broad tank. To watch liquid level in a tank, it is possible to pump out a part of liquid a suction. For pumping out of brake fluid to use a suction or a plastic bottle which intends only for brake fluid. Not to use drinking ware.

Brake fluid is poisonous and should not be sucked away by a mouth through a hose at all. After replacement of blocks the mark "MAH" in a broad tank as liquid when heating extends should not be exceeded. The following liquid flows down down on the brake cylinder, destroys a varnish and causes corrosion.

At strong wear of brake shoes to check ease of a piston stroke.

  1. For this purpose to insert a wooden core into a support and to ask the assistant to squeeze out slowly a brake pedal. The piston of a brake has to move forward and be moved easily. For check other support has to be removed. To watch that the piston did not start entirely. At a heavy piston stroke to repair a support (it is carried out in a workshop). If the piston incidentally jumps out, after installation of the piston the brake system has to be pumped over, see the Section Pumping of the Brake System.
  2. It is optional to implement the following item: For prevention of a scratch of disk brakes to cover the return and lateral faces of the basis of a brake shoe with protivoskripny paste (for example Plastilube, Tunap VC 582/S, Chevron SR/2, Liqui Moly LM-36 or LM-508-ASC). At the same time to apply lubricant only on a reverse side.

Paste should not get on a brake overlay or for a brake disk at all.

  1. If necessary paste to erase and clear the place alcohol at once.
  2. To insert both brake shoes with protivoskripny plates into a brake support.
  3. To check springs and pins of fastening of blocks, in case of strong corrosion and deformation to replace. To insert separate elements in the return sequence, see an illustration and an illustration. It is careful to hammer fastening pins with the hammer against the stop.
  1. Support for models from 10/89 g of the issue (except "univers"). To check the adjusting provision of springs of fastening. The external spring is in openings of pins of fastening.
  1. If were screwed, to unscrew wheel nuts. To screw a wheel, considering a tag on a nave. To lower the car and to tighten wheel nuts cross-wise with effort of 100 Nanometers.

Several times to squeeze out a brake pedal, notable resistance will not be felt yet.

  1. To check brake fluid in a compensation tank, if necessary to add to the mark Move.
  2. It is careful to earn extra new blocks, for this purpose several times to reduce car speed from 80 to 40 km/h small pressing of a pedal of a brake. In intervals to do pauses for cooling of brakes.

On the first 200 km it is not necessary to make full braking.
