Removal and installation of brake shoes of the parking brake
Parking brake
|
1 — the lever of the parking brake 2 — a cover 3 — a lock-nut 4 — an adjusting nut 5 — a bolt
|
6 — the switch of the parking brake 7 — a cable 8 — a collar 9 — the holder of a cable 10 — the plug |
|
1 — a cable 2 — a bolt 3 — a support 4 — a brake shoe 5 — the lock
|
6 — a finger 7 — the adjusting screw 8 — the bottom coupling spring 9 — the top coupling spring 10 — a compression spring 11 — a pin |
|
1. Remove a back brake disk. |
2. Disconnect a forward coupling spring. Check a spring. A spring with traces of a rust replace. |
|
3. Compress a face key of 5 mm a compression spring a little, turn on 90 ° and remove a spring from a block. |
|
4. Similarly remove springs from other brake shoes. |
5. Dissolve blocks above and remove them down. |
|
6. Check ease of a course of the lock. If necessary remove it. For this purpose pull a detail (1) down, squeeze out a finger (2) and remove a detail (3) from a cable. |
|
|
Installation
Brake shoes surely replace on both wheels at once.
|
1. Apply a thin film Molykote-Paste G greasings on sliding surfaces and a lock finger. |
2. Enter the lock with a finger (2) into a cable of a drive of the parking brake. |
|
3. Develop the device of adjustment of brake shoes (1). A carving slightly grease “Molykote” and turn again. 4. Establish the device of adjustment of brake shoes from below between blocks. Connect below a coupling spring (2) (a spring of smaller diameter). |
|
5. Insert brake shoes. Above they should enter into lock grooves. |
|
6. Compress two springs of brake shoes a face key of 5 mm, having at the same time turned them on 90 °. Marking is in a closed position on a bolt head, as is shown in an accompanying illustration. |
|
7. Hook nippers on the top coupling spring. |
8. Brake shoes (shooters on an accompanying illustration) should adjoin to a support of a brake board. |
|
9. Establish a brake disk and a back wheel. 10. Adjust the parking brake, address to the Section Adjustment of the parking brake. |
|
| If brake shoes of the parking brake were replaced, they should be earned extra on the road with not heavy transport traffic as follows: Since speed of 40 km/h carefully tighten the parking brake so that braking process began. Keeping speed, tighten a brake on one tooth and pass about 400 more m. Release a brake and let's to it be cooled. The specified process extra earnings irrespective of replacement of blocks is recommended to carry out once a quarter since thus from working surfaces of brakes the appeared rust and the postponed products of wear acts in film. |
