GENERAL INFORMATION

Prevention

At installation it is necessary to use new sealing washers under a connecting bolt of a brake hose.


MODELS WITH CONTINUOUS DISKS

Removal

PERFORMANCE ORDER
1. At existence remove wheel caps, then weaken bolts of fastening of forward wheels. Tighten the hand brake, then lift a forward part of the car and fix on supports. Remove a wheel.
2. Remove brake shoes.
3. 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.
4. Clear area round the connecting coupling of a brake hose and a support. Unscrew the connecting bolt, a fixing brake hose to a back part of a support and disconnect from a support a hose. Remove from a connecting bolt two sealing washers. Close an opening in a support and in a brake hose suitable jams.
5. Using a screw-driver edge as the lever, remove dustproof caps from two bolts of fastening of the holder of a support. Unscrew bolts and remove a support from a rotary fist.

Repair

Extraction of the plastic plug from a rubber protective cover

Arrangement of a rubber protective cover of an adjusting pin on a support on models with continuous brake disks

PERFORMANCE ORDER
1. Being careful and security measures, clear a support of a brake dust and dirt.
2. Fix the holder of a support in a vice with soft sponges and remove a support from the holder of a support for what press the support face down and remove it from adjusting pins. Note orientation and remove from the holder of a support directing springs.
3. Using a screw-driver edge as the lever, remove a bracket of fastening of a dustproof cover of the piston of a support, then, being careful, in the same way remove a dustproof cover.
4. Take the piston from a support for what it is possible to use air under the low pressure, submitted to the brake cylinder through an opening for connection of a brake hose. Thus instead of brake shoes establish wooden whetstone.
5. Remove wooden whetstone and, being careful, take the piston.
Using the wooden or plastic tool, take a sealing ring from a flute in a support opening.
6. Check a condition of all details of a support and replace the worn-out or damaged details. Check a condition of directing fingers.
7. Special attention turn on the cylinder and the piston. In the presence of scratches, рисок, wear or dot corrosion it is necessary to replace the piston and the cylinder, and it means that it is necessary to replace a support assembled. Irrespective of a condition, replace all rubber consolidations.
8. Wash out all details in methyl alcohol or pure brake liquid and wipe them. For pro-cleaning of tubes and openings use the compressed air.
9. Establish a sealing ring in a support opening.
10. Dip the piston into brake liquid and apply a thin film brake liquid on an opening for the piston in a support. Establish a dustproof cover on the piston so that internal diameter of a cover was included into a piston flute.
11. Insert the piston into a support and at the same time insert an external edge of a dustproof cover into a support before its fixing. Establish a bracket of fastening of a dustproof cover.
12. Check ease of moving of the piston in a support.
If necessary replace a rubber cover of an adjusting pin in the support case. Take from a pin the plastic plug, then, being careful, compress a rubber protective cover and take it from an opening in the support case (see fig. Extraction of the plastic plug from a rubber protective cover, the Arrangement of a rubber protective cover of an adjusting pin on a support on models with continuous brake disks).
13. In sequence, to return to removal establish new rubber protective covers.
14. Fix the holder of a support in a vice with soft sponges and establish directing springs in the same situation in which they were before removal.
15. Establish a support on adjusting pins of the holder of a support.

Installation

PERFORMANCE ORDER
1. Establish the holder of a support on a rotary fist and fix bolts, having tightened them the demanded moment. Establish on bolts dustproof caps.
2. Connect to a support a brake hose and fix it a connecting bolt with new sealing washers.
3. Establish brake disks.
4. Remove polyethylene from a jellied mouth of a popolnitelny tank and pump over the corresponding brake contour.
5. Establish a wheel and lower the car on the earth. Tighten bolts of fastening of a wheel the demanded moment.

MODELS WITH VENTILATED DISKS

Removal

Arrangement of bolts of fastening of the holder of a support to a rotary fist on models with ventilated brake disks

PERFORMANCE ORDER
1. At existence remove wheel caps, then weaken bolts of fastening of forward wheels. Tighten the hand brake, then lift a forward part of the car and fix on supports. Remove a wheel.
2. Remove brake shoes.
3. 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.
4. Clear area round the connecting coupling of a brake hose and a support. Unscrew the connecting bolt, a fixing brake hose to a back part of a support and disconnect from a support a hose. Remove from a connecting bolt two sealing washers. Close an opening in a support and in a brake hose suitable jams.
5. Remove a support.
If necessary unscrew two bolts and remove the holder of a support from a rotary fist (see fig. An arrangement of bolts of fastening of the holder of a support to a rotary fist on models with ventilating with my brake disks).
