Fig. Fig. 3 Measure the disc at the points given to determine if it is serviceable or needs refinishing or replacement

  1. With the wheel removed, check to see that there is no grease or other foreign material on the disc. If the disc is badly scored replace or refinish it. The minimum disc thickness is cast into the hub.
  2.  
  3. Measure the thickness of the disc with a micrometer at 12 points around the disc, 1 in. from the disc's edge. Any variation of more than 0.0005 in. means that the disc should be replaced.
  4.  
  5. Using a dial indicator, check the disc run out on both sides with the wheel bearing adjusted to zero end-play. Run out should be no greater than 0.004 in. If the run out exceeds this figure the disc should be refinished or replaced. Make sure the wheel bearing is properly adjusted when making this measurement.
