| 1. Remove a brake drum. |
| 2. Being careful and security measures, clear all traces of a brake dust from a brake drum, a brake board and колодок. |
| 3. Measure a thickness of overlays brake колодок in several points. If though one колодка is worn out in any place till the minimum thickness, replace all 4 brake колодки. |
|
4. Note adjusting position of all elements of a back brake. Using flat-nose pliers, remove a plate of a spring of fixing колодки, pressing a plate and turning it on 90 °. Remove springs and take clamp pins. |
| 5. Remove one brake колодку from the bottom support колодок and disconnect the bottom returnable spring. |
| 6. Wring out both колодки from the wheel brake cylinder and remove them. Thus do not damage пыльники. Disconnect a cable of a drive of a manual brake from brake колодки. For prevention of drop - out of pistons from the working brake cylinder fix pistons a corresponding elastic band or a wire. |
| 7. Note an arrangement of details of a regulator brake колодок, remove the lever of a drive of a manual brake and disconnect fixing spring of a bolt of a regulator from a lobby (on an arrangement) brake колодки. Disconnect the top returnable spring, separate forward brake колодку and a returnable spring from back brake колодки. Disconnect a spring, крепящую a regulator to back brake колодке (fig. the Arrangement of elements of adjustment brake колодок see). |
| 8. Replace all returnable springs irrespective of their condition. |
| 9. Unscrew a bolt of fastening of a regulator to an adjusting lath and check up their condition. Special attention turn on a carving of a bolt of a regulator and a side of an adjusting wheel. Pay attention that the left and right adjusting laths are not interchangeable. Bolts of a regulator of the right and left wheel also are not interchangeable. The bolt of a regulator of the left wheel has the left carving, and the bolt of a regulator of the right wheel has the right carving. |
| 10. Check up that all details on the end of an adjusting lath are correctly placed, then put a small amount of greasing with a fusion heat on a carving of a bolt of a regulator. Screw an adjusting wheel on a regulator bolt so that between a wheel and a bolt head there was a small backlash. Insert a regulator bolt into an adjusting lath. |
| 11. Establish a returnable spring on back (on an arrangement) brake колодку so that shorter hook of a spring incorporated with колодкой. Establish an adjusting lath by the spring end. Insert an adjusting lath into a groove in back brake колодке. |
| 12. Establish the top returnable spring on back brake колодку. The second end of a spring establish on a lobby brake колодку and, moving, arrange a lobby колодку so that the head of an adjusting bolt has settled down in a flute. After that insert a hook of a fixing spring into a groove on a lobby brake колодке. |
| 13. Raise rubber protective covers of the brake cylinder and check up the working brake cylinder on leaks of a brake liquid. |
|
14. Clear details of a back brake. On contact places колодок with a brake board put lubricant with a fusion heat. |
| 15. Check up that the lever of a manual brake is located opposite to an edge back brake колодки, and remove an elastic band, крепящую pistons in the brake cylinder. |
| 16. Stretch brake колодки and establish their top ends on the piston of the working brake cylinder. Connect a cable of a manual brake to the lever of a manual brake located on back brake колодке. Establish the bottom returnable spring on both brake колодки, establish the bottom part brake колодок on a support колодок. |
| 17. Moving brake колодки, centre them in relation to a brake board. Establish clamp pins колодки, a spring and a plate of fastening of a spring. |
| 18. Using a screw-driver, turn a wheel of an adjusting lath so that to unclench brake колодки to a contact of a brake drum. |
| 19. Establish a brake drum. |
| 20. Make replacement brake колодок on the second back wheel. |
| 21. After replacement brake колодок adjust a backlash between them and a brake drum for what some times press a brake pedal. By pedal pressing at normal work of an adjusting lath the clicks published by an adjusting lath should be audible. |
| 22. Check up and if it is necessary, adjust a manual brake. |
| 23. Check up level of a brake liquid in system. |
