  Q: How to inspect and refinish brake discs on a Ford Mustang?

  A: The manufacturer recommends using a specialized brake lathe to refinish brake discs while they are still installed on the vehicle. To inspect the discs, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the Brake Caliper and suspend it out of the way with wire. Reinstall the lug nuts to hold the disc against the hub and visually check for any score marks, cracks, or other damage. Deep score marks or cracks may require disc refinishing or replacement. To check disc runout, use a dial indicator and turn the disc. An indicator reading exceeding 0.003-inch may cause pulsation and require disc refinishing or replacement. The disc thickness should not be machined below the specified minimum refinish thickness, which can be checked with a micrometer. To remove and install the disc, remove the caliper mounting bracket and mark the disc in relation to the hub before removing it. Clean the hub flange and inside of the disc before installing it onto the hub assembly. Install the caliper onto the mounting bracket and tighten the bolts. Lower the vehicle, tighten the wheel lug nuts, and depress the brake pedal to bring the pads into contact with the disc. Check the brake operation before using the vehicle normally.
