PERFORMANCE ORDER
1. Turn off nuts of fastening of a wheel, lift the car and establish it on support. Remove a wheel and twirl two nuts for disk fastening.
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). It is not necessary to disconnect a brake hose.
3. After bolts of fastening of a support will be turned off, suspend a support on a piece of a wire so that it did not disturb 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 drawing) scratch – over 1,0 mm – demand removal of a disk and processing of its surface in a repair truck.
6. Check both parties of a disk. If when braking you tested twitching of a pedal of a brake, check disk palpation.
7. For check of palpation of a disk establish a tsiferblatny measuring instrument approximately in in 12,5 mm from external edge of a disk (drawing at the left). Establish the indicator on a zero and rotate a disk. Indications of the sensor should not exceed an admissible limit. If they exceed, the disk is necessary for restoring in a repair truck.

8. The surface of a disk is necessary for processing irrespective of indications of a tsiferblatny 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 surface of a disk, by means of an emery paper, deleting luster with roundabouts.
9. It is the 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 it is necessary to replace a disk) is designated on inside a disk.
10. The thickness of a disk can be checked by means of a micrometer.

Removal

PERFORMANCE ORDER
Turn off nuts which were established for deduction of a brake disk, and remove a disk from a nave.

Installation

PERFORMANCE ORDER
1. Establish a disk on bolts.
2. Establish the holder of blocks and a support on a brake disk and insert fastening bolts to a rotary fist or a nave arm. Tighten bolts of fastening of the holder of blocks and a support till the demanded moment of an inhaling (see tab. Moments of an inhaling of carving connections).
3. Establish a wheel, then lower the car on the earth. Tighten nuts of fastening of wheels till the demanded moment of an inhaling (see tab. Moments of an inhaling of carving connections). Squeeze out a brake pedal several times to grind in brake shoes to a disk. It is unessentially to carry out pumping of brake system, if the brake hose was not disconnected from a support. Check work of brakes before the beginning of normal operation of the car.
