 REMOVAL

1 Remove a back brake disk.

2 Disconnect by means of nippers a forward returnable spring, a spring with traces of corrosion or the weakened spring replace.

3 compress a spring a face key on 5 mm a little, turn on a corner 90 (1/4 turns) and remove a press spring with brake колодки.

4 Similarly remove a spring from another brake колодки.

5 Separate both brake колодки above and remove downwards.

6 Check up ease of a course of the lock, if necessary remove it. For this purpose pull an element-1 back, squeeze out a finger-2 and remove an element-3 from a cable.


 INSTALLATION

Necessarily replace brake колодки on both parties.
1 Slightly grease sliding surfaces and a finger of the lock with greasing “Molykote-Paste-G”.

2 Connect above the lock to a finger-2 with a cable of a drive of a brake.

3 Check up movement of the mechanism of adjustment brake колодок-1, slightly grease a carving with greasing “Molykote”. Turn on back a carving element.

4 Establish the mechanism of adjustment brake колодок below between brake колодками. Connect a returnable spring-2 (a spring of smaller diameter) with brake колодками. 3 – the top returnable spring.

5 Insert into place brake колодки. Above brake колодки should enter into grooves (arrows on an illustration) the lock.

6 Press two springs of compression by a face key on 5 mm and simultaneously turn on a corner 90 . In the closed position marks on a screw head cost, as is shown in an illustration.

7 By means of nippers for a brake spring connect the top returnable spring.

8 Brake колодки (arrows on an illustration) should adjoin to a support скобы brakes.

9 Establish to the place of 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, them it is necessary to earn extra on road with неинтенсивным transport as follows. Moving with a speed of 40 km/hour, cautiously tighten a lay brake so that easy braking was felt. At preservation of speed of movement tighten a brake on one tooth and pass so about 400 m. Release a brake and allow to it to be cooled. It is recommended to repeat this process once in three months irrespective of brake replacement so the rust which can be formed on a frictional surface, and deterioration products thus leaves.
