Check of a thickness of a brake disk

 PERFORMANCE ORDER

    Mark with an arrow a direction of rotation of a wheel. Turn away bolts of fastening of wheels. Lift and establish the car on supports.
    Measure a thickness of a brake disk necessarily in the most thin place (an arrow on an accompanying illustration). On HUNDRED for this purpose there is a special calliper or micrometric скоба since deterioration of a disk has an edge. It is possible to measure a thickness of a disk by means of a usual calliper. In this case on each party of a brake disk it is necessary to put a lining of a certain thickness (for example, a small coin). In this case it is necessary to subtract a thickness of two coins From the received result of measurement.

It is necessary to make measurement in several points of a brake disk.

    The sizes of a brake disk are resulted in Specifications.
    If a limit of deterioration of a disk will reach, it is necessary to replace necessarily both disks of one axis.
    In the presence of the big cracks or flutes, more a brake disk it is necessary to replace than 0.5 mm with depth.
    Observing a rotation direction, establish a wheel and fix it. Lower the car on wheels and only after that tighten bolts of fastening of a wheel cross-wise the moment 120Нм.
