1 — a cable
2 — a bolt
3 — a support
4 — brake колодка
5 — the lock

6 — a finger
7 — the adjusting screw
8 — the bottom coupling spring
9 — the top coupling spring

 REMOVAL

1. Remove a back brake disk.

2. Disconnect a forward coupling spring. Check up a spring. A spring with rust traces replace.

3. Compress a face key of 5 mm a compression spring a little, turn on 90 ° and remove a spring with колодки.

4. Similarly remove springs from others brake колодок.

5. Dissolve колодки above and remove them downwards.

6. Check up ease of a course of the lock. If necessary remove it. For this purpose pull a detail (1) downwards, squeeze out a finger (2) and remove a detail (3) from a cable.

Installation

Brake колодки necessarily replace on both wheels at once.

 INSTALLATION

1. Apply a thin film greasings “Molykote-Paste G” on sliding surfaces and a lock finger.

2. Enter the lock with a finger (2) into a cable of a drive of a lay brake.

3. Develop the device of adjustment brake колодок (1). A carving slightly grease “Molykote” and turn again.
4. Establish the device of adjustment brake колодок from below between колодками. Connect below a coupling spring (2) (a spring of smaller diameter).

5. Insert brake колодки. Above they should enter into lock grooves.

6. Compress two springs brake колодок a face key of 5 mm, simultaneously having turned them on 90 °. Marks are In the closed position on a bolt head, as is shown in an accompanying illustration.

7. Hook nippers on the top coupling spring.

8. Brake колодки (arrows on an accompanying illustration) should adjoin to a support of a brake board.

9. Establish a brake disk and a back wheel.
10. Adjust a lay brake, address to Section Adjustment of a lay brake.


If brake колодки a lay brake were replaced, they should be earned extra on road with not intensive transport movement as follows:
Since speed of 40 km/hour cautiously tighten a lay brake so that braking process has begun. Keeping speed, tighten a brake on one tooth and pass about 400 m. Release a brake and allow to it to be cooled. The specified process extra earnings irrespective of replacement колодок is recommended to spend once a quarter, since. Thus from working surfaces of brakes the appeared rust and the postponed products of deterioration acts in film.
