| 1. Turn off nuts of fastening of a wheel, lift the car and establish it on support. Remove a wheel and put two clamps for fastening of a disk. |
| 2. Remove a brake support, being guided by the instructions provided in (see subsection 9.4) (a disk of forward brakes) or (see subsection 9.6) (a disk of back brakes). The brake hose does not need to be disconnected. |
|
|
3. After bolts of fastening of a support are turned off, suspend a support on a piece of a wire so that it did not prevent further work, |
|
4. Turn off two bolts of fastening of the holder of blocks to a rotary fist or an arm of a nave and remove the holder of blocks. |
| |
5. Examine a surface of a brake disk on existence of scratches or other damages. Slight scratches and small flutes are normal and usually do not influence negatively work of brakes, but deep (as in the drawing) scratch – over 1,0 mm – demand removal of a disk and processing of its surface in auto repair shop. |
| 6. Check both parties of a disk. If when braking you experienced twitching of a pedal of a brake, check a disk beating. |
|
7. For check of a beating of a disk install the dial measuring instrument approximately in in 12,5 mm from an outer edge of a disk (the drawing at the left). Install the indicator on zero and rotate a disk. Indications of the sensor should not exceed an admissible limit. If they exceed, the disk needs to be restored in auto repair shop.

|
8. The surface of a disk needs to be processed irrespective of indications of the dial measuring instrument as it will create ideally smooth surface that guarantees good work of brakes. As a last resort, if you decide not to restore a disk surface then remove the luster formed on a disk surface by means of an emery paper, deleting luster with roundabouts. |
|
9. It is extremely important that after restoration of a surface of a disk its thickness did not decrease less admissible limit. Minimum admissible thickness of a disk (on reaching which the disk needs to be replaced) is designated on inside a disk. |
|
10. Thickness of a disk can be checked by means of a micrometer. |
