GENERAL INFORMATION

Prevention

It is necessary to replace brake shoes at once on two wheels – never replace brake shoes only on one wheel.

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.


PERFORMANCE ORDER
1. Remove a cap from a tank of brake liquid.
2. Turn off nuts of fastening of wheels, lift a back part of the car and establish it on support. Block forward wheels.
3. Remove a wheel and release the hand brake. It is necessary to replace at once all four brake shoes of back brakes. Not to mix them, work over each of wheels in turn.
4. Get the top and bottom bolts and remove a support from brake shoes and the holder of blocks (see fig. Elements of a support of back disk brakes).
5. Suspend a support on a suspension bracket spring by means of a piece of a wire; do not allow a support to hang on a brake hose and a rope of the hand brake.
6. Remove external antinoise laying and an external brake shoe, and then internal antinoise laying and an internal brake shoe.
7. Remove two fixing plates of brake shoes; examine them on existence of damages and replace, if it is necessary (good plates at installation on the holder of blocks should be latched; if they weakened or are deformed – replace them).
8. Carefully examine a brake disk, being guided by the instructions provided in subsection 9.7. If its surface needs processing, remove a disk, being guided by the instructions provided in the same section. At disk removal, it is possible to remove brake shoes also.
9. Establish fixing plates of the brake shoes, new brake shoes and laying. Check, that the ends of blocks were correctly established on fixing plates and establish an internal brake shoe so that the indicator of wear was from above.
10. Before support installation on new (thicker) brake shoes, it is necessary to take away back the self-regulating mechanism. For this purpose turn the support piston clockwise by means of the flat-nose pliers which sponges are established in lock flutes (1) on a piston surface. Continue to turn the piston while it will not begin to rotate freely, then combine lock flutes with a ledge (2) on a support.
11. Establish a support on brake shoes, having inserted a ledge on the back party of an internal brake shoe into a lock flute on the support piston.
12. Establish the top and bottom bolts and tighten them till the demanded moment of an inhaling (see tab. Moments of an inhaling of carving connections).
13. Establish a wheel, then lower the car on the earth. Tighten nuts of fastening of a wheel till the demanded moment of an inhaling (see tab. Moments of an inhaling of carving connections).

14. After completion of work, squeeze out a brake pedal several times for automatic adjustment of back brakes. Check level of brake liquid, having added it if it is necessary. Check work of brakes before the beginning of normal operation of the car.
