10.6. Brake disk

Check

PERFORMANCE ORDER
1. Release nuts of wheels, lift the car and establish on supports. Remove wheels and wrap nuts of wheels into place to record a disk concerning a nave (to provide application of effort to a disk it is possible to dress washers). Release the parking brake (when working on a back brake).
2. Remove a support (see subsection 10.5.), take aside and fix. Turn off bolts and remove a support arm.
3. Check a condition of a disk on both sides. At detection of traces of deep development (depth more than 1,0 mm), remove a disk and a proshlifuyta. If when braking pulsations were noted, then the raised disk beating can be the cause. In the drawing – a disk with traces from the slips which are worn out to rivets. Replace a disk with such defects.
4. Check a beating, having installed the arrow indicator in 13 mm from edge of a disk. If the beating on the indicator exceeds norm, then remove a disk and a proshlifuyta in car service.
