Replacement of brake shoes should be made at the same time on both forward/back brake mechanisms. Remember that developed in the course of operation of brake mechanisms the dust can contain extremely unhealthy the person asbestos. At all do not blow off a dust the compressed air and do not inhale it, - at service of mechanisms put on a protective mask or a respirator. At all do not use for rubbing of components of brake system gasoline or solvents on an oil basis, - apply only firm cleaners or methyl alcohol! |
1. Uncover the tank of brake liquid. Pump out from the tank about 2/3 containing in it hydraulic liquid.
2. Weaken nuts of fastening of the corresponding wheels. To Poddomkratta a car front/back also establish it on props, prop up protivootkatny boots wheels standing on the earth.
3. Remove forward/back wheels.

Replacement of all four blocks of brake mechanisms of both wheels of one axis should be made at the same time. In order to avoid confusion work with each mechanism in an individual order, - the second in case of need can be used as an example at assembly. |
4. Attentively examine a brake disk (see. Section condition Check, removal and installation of a brake disk). In case of need pro-point performance, the disk also should be removed (see below).
5. At performance of replacement of blocks of brake mechanisms of forward wheels follow the instructions provided on illustrations below, - attentively study explanatory signatures to pictures.

|
Before dismantling the brake mechanism should be cleared carefully with application of special means, then to dry; at all do not blow off a brake dust the compressed air! |
|
|
Wring out the piston in the support cylinder by means of a clamp (the basic end of a clamp is got for a support, screw - rests against an external brake shoe) |
|
|
Turn out the bottom bolt of fastening of a support (And); the top bolt (In) should be turned out only in a case when the support needs removal. A hollow bolt of shtutserny connection (C) is subject to an otdavaniye only for support replacement |
|
|
Lift a support, having removed it from a brake disk |
|
|
On models since 1995 вып. remove antivizgovy springs |
|
|
Take an internal brake shoe |
|
|
Remove an anchor bracket the top and bottom holders of blocks |
|
|
Remove from blocks adjusting slips |
|
|
Wipe directing finger of a support, examine it on existence задиров and traces of development of corrosion, then grease with refractory greasing and establish on the regular place in an anchor bracket |
|
|
Establish on blocks adjusting slips |
|
|
Grease with antivizgovy structure reverse sides of both blocks, let's to structure stiffen within several minutes |
|
|
Establish the top and bottom holders of blocks |
|
|
Establish an internal block (this block is equipped with the wear indicator) |
|
|
Establish an external block |
|
|
On models since 1995 вып. establish antivizgovy springs, then (on all models) lower a support, screw the bottom fixing bolt and tighten it with demanded effort.
|
|
If it is not possible to put on a support blocks, wring out the piston in the cylinder by means of a clamp. |
|
6. Procedure of replacement of blocks on back disk brake mechanisms is stated in illustrations below.
|
|
Having cleared assembly of a brake dust, release a clamp of a cable of the parking brake (And) and disconnect a cable from the executive lever. On models since 1995 вып. turn out the top bolt of a support (And) (on earlier models turn out a bolt C); a hollow bolt of shtutserny connection (C) is subject to an otdavaniye only for support replacement |
|
|
Remove a support from a brake disk and the brake shoes placed in an anchor bracket; take an internal block |
|
|
Remove the top and bottom holders of blocks |
|
|
Remove from a support antivizgovy springs and attentively check their condition; in case of identification of cracks or other mechanical damages replace springs |
|
|
Remove from blocks adjusting slips |
|
|
Wipe directing finger of a support, examine it on existence задиров and traces of development of corrosion, then grease with refractory greasing and establish on the regular place in an anchor bracket |
|
|
Establish on blocks adjusting slips |
|
|
Grease with antivizgovy structure reverse sides of both blocks, let's to structure stiffen within several minutes |
|
|
Establish the top and bottom clamps of blocks |
|
|
Establish an external block |
|
|
Establish an internal block |
|
|
Rotating the piston, drown it in the support cylinder (use the special adaptation - ask in shops of automobile accessories, as a last resort it is possible to use nippers). Lower a support in regular situation, return a fixing bolt and tighten it with demanded effort, then connect to the executive lever of the brake mechanism a driving cable of the parking brake |
7. At assembly track, that the fixing bolt was tightened with demanded effort.
8. Having finished assembly, several times squeeze out a pedal of a foot brake for a usadka of new blocks on disks. Check level of brake liquid, in case of need make the corresponding adjustment (see. Head of Control and routine maintenance). Before starting normal operation of the car, make sure also serviceability of functioning of brake system. |
