  Q: What is the Inspection Procedure for a Disc Brake Rotor on Buick Century,Regal?

  A: Raise the car, support it with jack stands, and remove the wheel and tire assembly. Remove the brake caliper, and support with wire. Remove the dust cap and remove the cotter pin and the bearing retaining nut. Remove the outer wheel bearing and place it in a clean location. Remove the wheel bearing, hub, and disc assembly from the spindle. Installation is in the reverse order of removal. Check the disc for any obvious defects such as excessive rust, chipping, or deep scoring. Make sure there is no wheel bearing play by performing the wheel bearing adjustment procedure. Then, check the disc for run-out by installing a dial indicator on the caliper so that its feeler will contact the disc about one inch below its outer edge. Turn the disc and observe the run-out reading. If the reading exceeds 0.002 in. (0.05mm), replace the disc. Check the caliper thickness with a vernier caliper or other appropriate tool. Minimum thickness dimensions are cast into the disc. Adjust the wheel bearings.
