GENERAL INFORMATION

Prevention

The brake liquid used in hydraulic system of coupling is poisonous, therefore at its hit on skin it is necessary to wash out immediately this place a plentiful quantity of water. If liquid got to eyes or in an organism, it is necessary to address immediately to the doctor. Some liquids have property easily to ignite and can light up even from contact to hot knots of the car. Besides, the liquid used in hydraulic system of coupling, dissolves paint and plastic therefore at liquid hit on a paint and varnish covering of the car wash out it a plentiful quantity of water. Also this liquid is hygroscopic, i.e. absorbs moisture from air and therefore the liquid, being stored in open ware, it is not recommended to use a long time.

At work of brake shoes the brake dust which contains asbestos, unhealthy forms. Therefore when cleaning brake shoes do not use the compressed air and do not inhale a dust.


Removal
Prevention

At installation of a support it is necessary to use new bolts of fastening of a directing finger on models with a mobile support with one piston and new bolts of fastening of a support on models with a motionless support with two pistons.


PERFORMANCE ORDER
1. Tighten the hand brake, then lift a forward part of the car and fix on supports. Remove the corresponding forward wheel.
2. For reduction of losses of brake liquid uncover a popolnitelny tank of brake system, close a tank mouth polyethylene and again screw a cover. It is necessary in order that the cover tightly closed a popolnitelny tank. Alternatively, using a clip, press the brake hose going to a support.
3. Clear area round the connecting coupling of a brake hose and a support. Weaken the connecting coupling, fixing a brake hose to a support.
4. Remove brake shoes.
5. On models with a mobile support with one piston unscrew the top bolt of fastening of a directing finger. Then screw together a support from a brake hose and take it from under the car.
6. On models with a motionless support with two pistons unscrew two bolts, fixing the holder of a support to povorotno му to a fist. Remove a support and screw together it from a brake hose. At installation it is necessary to use new bolts of fastening of a support to a rotary fist.
