Replacement колодок disk brake mechanisms of forward 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

Cock a lay brake, поддомкратьте redock of the car and establish it on props. Remove forward wheels.

By means of small шлицевой screw-drivers take from an aperture about a support the deterioration gauge колодок (1) and take him aside.

Remove the big spring clip from a support, — be attentive, in avoidance соскакивания springs before to hook its screw-driver cover with its rags.

B — Removal of a fixing spring from a support of the forward brake mechanism on models Zafira

Remove dustproof caps of apertures of directing fingers of a support.

Turn out directing bolts and remove a support with колодками with анкерной скобы or nave carriages (depending on a way of execution). Tie up a support to a rack a wire piece, — do not leave its hanging on a hose.
Take from a support external колодку, then remove internal колодку, kept by the metal spring attached to its basis.
1 — Internal колодка
2 — External колодка

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.
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. At an input of the indicator of deterioration колодок in contact to a disk (on the panel of devices the control lamp works), also it is necessary to replace it.
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.
Directing fingers should move easily 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.

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. Отжимание the piston it is made by means of special adaptation Vauxhall 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.

Fill in a support internal brake колодку, having planted its spring in deepening in a face surface of the piston.

Internal and external колодки differ from each other on a design, — pay attention to marks in the form of an arrow, put on the basis колодки, — the arrow should specify in a direction of rotation of a disk at car movement by a forward course.

Establish on a support external колодку, a frictional overlay to a disk, колодка it is equipped by the acoustic alarm spring (1) warning the driver about deterioration колодки.

Establish floating скобу with internal колодкой over external колодкой and lay it on an arm.
Screw bolts of directing plugs and tighten them with demanded effort.
Establish пыльники.
Establish a support spring, having got its ends in apertures in скобе.

Springs of two types are used, - one is connected to a support, another — to fastenings on external колодке. If the spring of last type is established, at first connect it to колодке, then get for ledges on a support.

Establish into place the deterioration gauge колодок.
Some times squeeze out a pedal of a foot brake before occurrence of sensation of hardness of a course.
Operating in a similar manner, make replacement колодок the brake mechanism of an opposite wheel.
Establish wheels, lower the car on the earth and tighten wheel bolts with demanded effort.
Check up level of a brake liquid, in case of need make corresponding updating (Routine maintenance see the Head).
