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 from a brake shoe.

4 Similarly remove a spring from other brake shoe.

5 Separate both brake shoes above and remove down.

6 Check 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

Surely replace brake shoes on both parties.

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

6 Press two springs of compression by a face key on 5 mm and at the same time turn on a corner 90 °. In a closed position marking on a screw head costs, as is shown in an illustration.

If brake shoes of the parking brake were replaced, them it is necessary to earn extra on the road with not heavy traffic of transport as follows. Moving with speed of 40 km/h, carefully tighten the parking 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 let's to it 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 wear products thus is removed.
