Replacement колодок disk brake mechanisms of back wheels

In order to avoid car withdrawals aside during braking replacement brake колодок should be made simultaneously on both forward / back brake mechanisms. Remember that developed in the course of work 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 spirit!


 PERFORMANCE ORDER

  1. Prop up forward wheels противооткатными boots, поддомкратьте a back of the car and establish it on props. Remove both back wheels.
  2. Completely release a lay brake and ослабьте приводной a cable by отдавания 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, keeping directing pin from проворачивания a brace. Remove a brace.

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

  1. Develop a support upwards on an axis top directing and remove колодки.

    A — Removal external колодки
    B — Removal internal колодки

B.
  1. Сметите from components of the brake mechanism accumulated on from surfaces a dust (the prevention in the beginning see). Wipe a support and a face surface of the piston pure rags. Remove a rust from edge of a brake disk.
  2. Measure a thickness of everyone колодки, not including a metal substrate. If any колодка it is damaged, or it is worn out over an admissible limit (Specifications see), replace all complete set колодок, both forward wheels. Made oily колодки are subject to replacement without fail, - preliminary eliminate the reason of development of leak.
  3. If the condition brake колодок is found satisfactory, carefully clear them of a dirt a soft wire brush, special attention giving back and to lateral faces. Clean flutes in frictional overlays, completely having removed from them extraneous inclusions. Smooth out seats колодок in a support and анкерной скобе.
  4. Directing fingers should move freely in support plugs. Grease the back parties колодок with copper greasing. Check up a condition established on the piston пыльника, examine the piston on presence of signs of development of leaks of a brake liquid, traces of corrosion and mechanical damages. In case of need make necessary regenerative repair (Removal, regenerative repair and installation of supports of disk brake mechanisms of forward wheels see). Defective components replace.
  1. At installation new колодок, the piston is necessary for drowning in the cylinder of a support for the purpose of clearing under installation thicker new колодок, - cut on the piston should be combined with a ledge on remove. Отжимание the piston it is made by means of the special adaptation (1) though the clamp approaching on the size or the wooden lever will not less effectively work also. If tank GTTS is not filled up to the top, отжимание the piston should not lead вытеканию from it to a brake liquid, however, it will be preliminary reasonable to check up its level, - in case of need pump out surplus.

Отжимание the piston it is interfaced to risk of damage of a sealing cuff. Composers of the present Management recommend to press a brake hose a clamp and to pit a liquid through the prorolling union, preliminary having released it on a half-turn.

  1. Turning the piston, achieve cut combination in its face surface with a ledge on a support.
  1. Develop a support upwards, establish in анкерную скобу new колодки frictional overlays to a disk. The acoustic alarm spring of deterioration (1) is established on internal колодку.
  1. Lower a support on колодки. Clean a carving of the bottom bolt a wire brush, or "banish" it леркой. Slightly grease a carving part of a bolt with fixing hermetic, then screw a bolt and tighten it with demanded effort, keeping directing pin from проворачивания рожковым a key.
  2. Plant приводной a cable of a manual brake in an arm of a support and fix its brace.
  3. Wring out the executive lever and connect to it a cable tip.
  4. Some times squeeze out a pedal of a foot brake before occurrence of sensation of "hardness" of its course.
  5. Operating in a similar manner, make replacement колодок the brake mechanism of an opposite wheel.
  6. Make adjustment приводного a cable of a lay brake (Adjustment of a drive of a lay brake see).
  7. Establish wheels, lower the car on the earth and tighten wheel bolts with demanded effort.
  8. Check up level of a brake liquid, in case of need make corresponding updating (Routine maintenance see the Head).
