Prevention

The dust formed as a result of wear of brake shoes, contains the asbestos which is hazardous to health. Do not blow off it by means of the compressed air and do not inhale.

It is forbidden to use solvents on the basis of gasoline for cleaning of the mechanism of brakes. Use only a special cleaner for the mechanism of brakes.

If it is necessary to carry out a support partition (usually because of leakage of brake liquid) previously learn the price of spare parts or cost of already vosstavlenny or new support. Before the beginning of a partition get a repair set. Always repair both supports together – never repair only one of them.


Removal

PERFORMANCE ORDER
1. Turn off nuts of fastening of wheels, lift a back part of the car and establish it on support. Remove a wheel.
2. Turn off a bolt and disconnect a brake hose from a support. Close a hose opening by means of a piece of a rubber hose of suitable diameter for prevention of hit of dirt and moisture in brake system, and also for reduction of losses of brake liquid.
3. Disconnect a rope of the hand brake from a support, having got the check and a pin, thus press on the cranked lever of the hand brake. Remove a fixing clip of a braid of a rope and remove a rope.
4. Remove a support, being guided by the instructions provided in subsection 9.3 (removal of a support is a part of operation on replacement of brake shoes).

Partition

PERFORMANCE ORDER
1. For a partition of a support squeeze out plugs from ears of a support and remove dustproof covers and covers of bolts from both parties of a support.
2. By means of a screw-driver remove a fixing ring of a cover of the cylinder and a cover.
3. By means of flat-nose pliers with thin sponges which are necessary for inserting into flutes on a piston surface, turn the piston counter-clockwise and get it from a support.
4. Examine a surface of the piston and walls of the cylinder of a support. If they are scratched, on them is watch corrosion or wear, replace a support together with the piston.
5. If these elements in a good condition, remove piston consolidation from the support cylinder by means of the wooden or plastic tool. Metal tools can damage a cylinder surface.
6. The partition of the hand brake and elements of the self-regulating mechanism is not recommended, as existence of special tools and many spare parts for this purpose is necessary are not on sale separately. Check operation of the adjusting mechanism, having pressed the cranked lever of the hand brake a hand, and, having checked, that the adjusting bolt moved evenly. If any of elements of the adjusting mechanism it is faulty, replace a support.
7. Clear all elements by means of cleaning liquid for the mechanism of brakes.
8. For assembly of a support it is necessary to get a repair kit.
9. Omit new consolidation of the piston in brake liquid and establish it in the support cylinder.
10. Lower the new piston in brake liquid and establish it on an adjusting bolt in the support cylinder. By means of flat-nose pliers with thin sponges which are necessary for inserting into lock flutes of the piston, turn the piston clockwise until it will not begin to rotate freely, then combine lock flutes with a ledge on a support.
Establish a new dustproof cover of the piston and a fixing ring.
Grease plugs with silicone greasing (it should be included in a repair kit) and establish them in support ears. Establish dustproof covers and covers of bolts.

Installation

PERFORMANCE ORDER
1. Installation of a support is carried out upside-down removals. Do not forget to replace copper sealing washers (laying) on connection of a brake hose (new washers are usually included in a repair set).
2. Pump over a contour of brake system, being guided by instructions (see subsection 9.12). Check, that connections of brake hoses did not proceed. Check work of brakes before the beginning of normal operation of the car.
