Removal and installation of blocks of a back disk brake

Back disk brakes are established on cars with big engine capacity and/or ABS. For a vvinchivaniye of the piston of a brake the special adaptation is necessary. If the special adaptation is not present, it is possible to make something similar or to address in a workshop.



    To mark the provision of a disk of a back wheel concerning a nave that it was possible to establish an otbalansirovanny wheel in former situation. To weaken nuts of a wheel of the car standing on the earth. To remove a wheel.

Change by places of blocks of the right and left wheels is inadmissible. Change by places can lead to non-uniform brake influence. It is obligatory to replace at the same time all blocks of one axis even if the limit of wear were reached by only one block. If blocks are established again, before removal it is necessary to mark them.

    Cars from 10/89 g вып., except the versatile person models: Slightly to screw 2 nuts of a wheel, to stop a brake disk. To release the hand brake.
    Cars to 9/89 g вып. and versatile person models: To unscrew the bottom directing finger of the case of a support. On cars from 10/89 g вып.: To unscrew the top directing finger, in addition to release a brake hose from directing on an amortization rack.
    To cast away the piston case up and to suspend on a wire to a body that the brake hose was not loaded.

Brake hose not to remove, differently the system will be necessary for pumping over.

    Cars to 9/89 g вып. and versatile person models: to take out brake shoes with 2 top and bottom springs and 2 protivoskripny plates.
    Cars from 10/89 g вып., except the versatile person models: To take out a spring - 3-screw-driver from openings of brake shoes. Then to take out blocks-4-together with springs-6-and a protivoskripny plate-5-.


At the removed brake shoes not to press a brake pedal, differently the piston it will be squeezed out from the case. If the piston is squeezed casually out, to insert it in MAZDA workshop.


    To clear directing surfaces and places of landing of blocks in mine of the case a suitable soft metal brush or to wipe a rag with alcohol. Not to apply containing mineral oils solvents or tools with keen edges. Before installation of blocks it is necessary to check a brake disk on existence of grooves, having felt it fingers. With grooves it is necessary to replace brake disks. To measure thickness of a brake disk. To check on existence of cracks a boot and protective cuffs in a support. It is obligatory to replace the damaged cap, as getting dirt quickly will lead to a support leakage. For this purpose the brake support should be removed and disassembled (is carried out in a workshop).
    Slowly to screw the piston to the right, clockwise, by means of the special adaptation, against the stop. Then to turn the piston so that grooves stood directly.

The piston of a brake should be screwed in. If it is simple for moving, adjustment of the hand brake in a support will automatically collapse.

    The special tool for a vvinchivaniye enters into persistent grooves so the piston can be turned. If the special adaptation is not present, it is possible to make something similar by own efforts or to address in a workshop.

At a piston vvinchivaniye brake liquid 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 liquid to use a suction or a plastic bottle which intends only for brake liquid. Not to use drinking ware.

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

    It is unessentially to carry out the following item: For предотвращеня a scratch of disk brakes to cover return and lateral faces of the basis of a brake shoe with protivoskripny paste (for example Plastilube, Tunap VC 582/S, Chevron SRJ/2, Liqui Moly LM-36 or LM-508-ASC). Thus to put greasing only on a reverse side.

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

    If necessary paste at once to erase and clear a place alcohol. To establish on brake shoes new springs, see illustrations in the paragraph Removal.
    To insert both brake shoes with protivoskripny plates and to cast away the piston case down. Thus camber on an internal brake shoe will be included into a persistent groove of the piston. At an otkidyvaniye down to watch, that the cuff was not damaged.
    Cars from 10/89 g вып., except the versatile person models: To insert a spring-3-into openings of brake shoes.
    To screw bottom, on cars from 10/89 g вып. the top directing finger on the holder of a support with effort of 20 Nanometers. To fix a brake hose in fastening on an amortization rack.
    If were established, to unscrew wheel nuts. To screw a wheel, considering thus a label on a nave. To lower the car and to tighten nuts cross-wise with effort of 100 Nanometers.

Several times to squeeze out a brake pedal, notable resistance will not be felt yet. At the expense of it the adjusting device of the parking brake is established.

    To check brake liquid in a compensatory tank, if necessary to add to the maximum mark. To adjust the hand brake, see. Section Adjustment of the hand brake. Carefully to earn extra new blocks, for this purpose several times to reduce speed of the car with 80 to 40 km/h in 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 complete braking.
