PERFORMANCE ORDER

Processing of brake disks is not allowed. In the presence of grooves 0,5 mm are deeper or strong wear the disk should be replaced. Thus always to replace both disks on one axis.

In workshops the special measuring instrument or a micrometer as because of wear on a brake disk the edge is formed is for this purpose used. It is possible to measure thickness of a disk also by a usual calliper, however from each party of a disk it is necessary to enclose laying of known thickness. For determination of exact thickness of a disk it is necessary to subtract total thickness of laying from the received value. Measurement to make in several points of a disk.
