The prevention Disks of brakes (forward or back) should vary or be ground in steam.
Check
| PERFORMANCE ORDER |
| 1. Release bolts of fastening of wheels, lift the car and establish on supports, remove a wheel and wrap three bolts in a disk. At work with a back brake disk include a manual brake. |
|
2. Remove a support, take aside and fix, without disconnecting a hose. Turn away bolts (arrows) and remove a support arm. |
| 3. Check up a disk surface on presence of cracks, deterioration and other damages. Presence of superficial damages and easy scratches is supposed. In the presence of deep задиров, it is necessary to replace a disk, or прошлифовать. If on a disk there are cracks replace it. |
|
4. Check up both parties of a disk. If at inclusion of brakes strong vibration, that, probably is found out, the disk is jarred on (disk palpation is very great). On cars with ABS-system the vibration caused короблением, it is possible to accept for normal work of ABS-system (by pressing a brake pedal almost same vibration is felt, as at a faulty disk). |
|
5. Check up disk palpation, having established an indicator leg in 13 mm from edge of a disk and rotating a disk. If palpation exceeds norm replace a disk or прошлифуйте. |
|
6. The disk is recommended to be ground in any case, at least to remove roughnesses a small emery paper. |
|
7. Disk polishing if its thickness becomes less limiting is not supposed. The limiting thickness of a disk is stamped on a part of a disk which fastens to a nave. |
