9.9.3. Replacement of a brake disk

In the presence on a working surface of a disk of zadir, deep рисок and other defects increasing wear of blocks and reducing efficiency of braking and also in case of the raised side beating of the disk causing vibrations when braking, replace a disk. In specialized workshops such disk can be pierced and proshlifovat on both sides on identical depth, but after processing thickness of a disk has to be not less minimum admissible. Minimum admissible thickness of a brake disk is 19 mm. If thickness of one of disks is less than specified value, replace both disks. When replacing brake disks surely replace brake shoes with a new set.

It will be required to you: a key hexagon "on 10", a key for bolts of wheels, the screw-driver with a crosswise edge.

1. Remove a wheel.

2. Remove a support in collecting (see. "Replacement of a support of the forward brake mechanism"), without disconnecting a brake hose, also fix by a wire. At the same time do not allow twisting or a tension of a hose.	3. Turn out the lock screw...

4. … also remove a brake disk.

5. Similarly remove the right brake disk.

6. Establish details as it should be, the return to removal.

NOTE Before installation of a disk carefully clear privalochny surfaces of a nave and a disk of a rust and scale as even the smallest particle clamped between privalochny surfaces will cause a beating of a disk and vibration when braking.

    

GOOD ADVICE If you establish a former disk, remove with a file the fillets on working surfaces of a disk formed as a result of wear of a disk on both sides.
