BMW 3 series E46

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 pads.

4 Similarly remove a spring from another brake pads.

5 Separate both brake pads 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.

Necessarily replace brake pads 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 Pad-1, slightly grease a carving with greasing “Molykote”. Turn on back a carving element.

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

5 Insert into place brake pads. Above brake pads 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 pads (arrows on an illustration) should adjoin to a support скобы brakes.

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.
