Check

PERFORMANCE ORDER
1. For check of brake shoes it is recommended to remove a brake drum. In this case it is possible to check a condition of the working brake cylinder also.
2. Wear of overlays of brake shoes can be checked and without removal of a brake drum through viewing openings in a brake board after removal of a cap from an opening.
3. Using a small lamp and a mirror, through an opening in a brake board check thickness of an overlay of a brake shoe.
4. Even if the limit of wear were reached by only one brake shoe, surely replace all back brake shoes in a set.

Replacement

PERFORMANCE ORDER
1. At existence remove caps of back wheels, then weaken bolts of fastening of wheels.
2. Lift a back part of the car and fix on supports.
3. Remove back wheels.
4. Completely release the hand brake.
5. Unscrew the screw of fastening of a brake drum and remove a brake drum.
6. If the brake drum is kept by brake shoes, remove a cap from a viewing opening of a brake board and through an opening move a control lever of the hand brake to a brake shoe, thus brake shoes will depart from a drum and the drum will easily act in film.
7. Note the adjusting provision of all elements of a back brake.
8. Measure thickness of a frictional overlay of a brake shoe and at wear it in any point till minimum admissible thickness replace all four brake shoes.
9. Also it is necessary to replace blocks, if though one of blocks is polluted by oil as there is no way of degreasing of brake shoes.
10. If brake shoes are non-uniformly worn-out or polluted by oil, reveal and eliminate the reason of it before installation of new brake shoes.
11. Using flat-nose pliers, remove a plate (it is specified by an arrow) springs of fixing of a block, pressing a plate and turning it on 90 °.
12. Remove a spring and take clamp pins.
13. Disconnect from a control lever a cable of the hand brake (the arrow specified cable fastening to the lever of the hand brake).
14. Disconnect from brake shoes the top returnable spring and remove blocks from a brake board.
15. If necessary remove brake shoes together with a spring and a razzhimny level.
16. Remove a nave. Be careful not to damage rubber covers of the working brake cylinder. Before removal note the provision of a returnable spring and an adjusting level.
17. Do not remove at the same time brake shoes of the left and right back wheel not to mix a detail of brake shoes.
18. For prevention of an exit of pistons from the working brake cylinder establish on pistons an elastic band or fix them a spring bracket. Do not press a brake pedal at the removed brake drum.
19. Being careful and security measures, clear all traces of a brake dust from a brake board.
20. Apply a thin film high-temperature greasing on places of contact of brake shoes and a brake board.
21. If on overlays of brake shoes there is a liquid which has flowed out from the working brake cylinder or the bearing of a nave, define the reason of an effluence and eliminate it.
22. If brake shoes acted in film assembled, note the provision of elements and separate from each other brake shoes, springs and a razzhimny level.
23. If brake shoes of the left and right back wheel acted in film at the same time, do not mix a detail. Cores with a carving of adjusting levels of the left and right wheel are noted by letters L or R, and other details are identified by color: the black – for the left side and silvery for the right side.
24. Disassemble and clear an adjusting level.
25. Check a condition of returnable springs and, if necessary, replace them.
26. If on new brake shoes there is no control lever of the hand brake remove it from an old brake shoe and establish on the new.
27. Fix a sharnirny finger of a control lever of the hand brake a spring ring.
28. If elements of a back brake are established assembled, collect new brake shoes, springs and an adjusting level.
29. For simplification of installation move apart an adjusting razzhimny level.
30. Establish on brake shoes the top returnable spring.
31. Establish on a leading brake shoe a spring of the lever of a regulator (the arrow specified the installation direction).

35. Rotating a wheel of an adjusting level, reduce length of a razzhimny level to take away brake shoes from a brake drum.
36. Check that the reference point of a stop of the lever of the hand brake is established against edge of a brake shoe, then establish a brake drum.
37. Make replacement of brake shoes on the second back wheel.
38. After replacement of brake shoes adjust a gap between them and a brake drum for what 15–20 times press a brake pedal. By pedal pressing at normal work of an adjusting level the clicks published by an adjusting level should be audible.
