9.8.3. 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 value.
Minimum admissible thickness of a brake disk of the brake mechanism of a forward wheel of 23 mm. If thickness of one of disks is less than specified, replace both disks. When replacing brake disks surely replace brake shoes with a new set.
It will be required to you: a face head "on 15", a key for nuts of wheels.
1. Remove a wheel from the replaced disk.
2. Remove a support in collecting (see. "Replacement of a support assembled from a guide of blocks"), without disconnecting a brake hose, also fix it by a wire, without allowing twisting or a tension of a hose.
3. Remove a brake disk.
4. Similarly remove a brake disk of the second brake mechanism.
5. 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.
