Replacement of blocks of disk brake mechanisms of back wheels

In order to avoid car withdrawals aside during braking 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!


 PERFORMANCE ORDER

  1. Prop up forward wheels protivootkatny boots, поддомкратьте a back of the car and establish it on props. Remove both back wheels.
  2. Completely release the parking brake and weaken a driving cable by an otdavaniye of an adjusting nut.
  1. Screw-driver wring out the executive lever on a support of the brake mechanism of a back wheel and disconnect from it a cable tip, release a clamp and liberate a cable from a basic arm.
  2. Turn out the bottom bolt of fastening of a support, holding directing pin from a provorachivaniye a brace. Remove a brace.

    1 — the Executive lever
    2 — the Clamp of fastening of a cable in a basic arm
    3 — Nizhny a bolt of fastening of a support

  1. Develop a support up on an axis top directing and remove blocks.

    A — Removal of an external block
    B — Removal of an internal block

  1. To Smetita from components of the brake mechanism accumulated on from surfaces a dust (see the prevention at the beginning). Wipe a support and a face surface of the piston pure rags. Remove a rust from edge of a brake disk.
  2. Measure thickness of each block, not including a metal substrate. If any block is damaged, or is worn-out over an admissible limit (see. Specifications), replace all set of the blocks, both forward wheels. Greasy blocks are subject to replacement without fail, - previously eliminate the reason of development of leak.
  3. If the condition of brake shoes is found satisfactory, carefully clear them of dirt a soft wire brush, special attention giving back and to lateral faces. Clean flutes in frictional slips, having completely removed from them extraneous inclusions. Smooth out seats of blocks in a support and an anchor bracket.
  4. Directing fingers should move freely in support plugs. Grease the back parties of blocks with copper greasing. Check a condition of a boot established on the piston, examine the piston on existence of signs of development of leakages of brake liquid, traces of corrosion and mechanical damages. In case of need make necessary regenerative repair (see. Removal, regenerative repair and installation of supports of disk brake mechanisms of forward wheels). Defective components replace.
  1. At installation of new blocks, the piston is necessary for drowning in the support cylinder for the purpose of release under installation of thicker new blocks, - cut on the piston should be combined with a ledge on remove. Otzhimaniye of the piston is made by means of the special adaptation (1) though will not less effectively work and a clamp suitable on the size or the wooden lever. If the GTTs tank is not filled up to the top, the otzhimaniye of the piston should not lead to an effluence from it some brake liquid, however, reasonably previously to check its level, - in case of need pump out surplus.

By Otzhimaniye of the piston it is interfaced to risk of damage of a sealing cuff. Originators of the real Management recommend to press a brake hose a clamp and to pit liquid via the pumping union, previously having released it on a half of turn.

  1. Turning the piston, achieve cut combination in its face surface with a ledge on a support.
  1. Develop a support up, establish in an anchor bracket new blocks frictional slips to a disk. The acoustic alarm spring of wear (1) is established on an internal block.
  1. Lower a support on blocks. Clean a carving of the bottom bolt a wire brush, or "banish" it a lerka. Slightly grease a carving part of a bolt with fixing hermetic, then screw a bolt and tighten it with demanded effort, holding directing pin from a provorachivaniye a rozhkovy key.
  2. Plant a driving cable of the hand brake in an arm of a support and fix it a brace.
  3. Wring out the executive lever and connect to it a cable tip.
  4. Several times squeeze out a pedal of a foot brake before emergence of feeling of "hardness" of its course.
  5. Operating in a similar manner, make replacement of blocks of the brake mechanism of an opposite wheel.
  6. Make adjustment of a driving cable of the parking brake (see. Adjustment of a drive of the parking brake).
  7. Establish wheels, lower the car on the earth and tighten wheel bolts with demanded effort.
  8. Check level of brake liquid, in case of need make the corresponding adjustment (see. Head Routine maintenance).
