  Q: How to inspect and replace brake discs?

  A: To inspect the brake disc, begin by loosening the wheel lug nuts, raising the vehicle, and securely supporting it on jack stands. Remove the wheel and install the lug nuts to hold the disc in place. Proceed to remove the Brake Caliper, suspending it out of the way with a wire without disconnecting the brake hose. Remove the torque plate mounting bolts and detach the torque plate. Perform a visual inspection of the disc surface, checking for score marks, damage, and deep scoring. It is essential to examine both sides of the disc. To assess disc runout, position a dial indicator about 1/2-inch from the outer edge of the disc, set the indicator to zero, and rotate the disc. The indicator reading should not exceed the specified allowable runout limit. If it does, the disc needs refinishing. Take care not to machine the disc below the specified minimum refinish thickness. The minimum wear thickness can be verified using a micrometer. For removal, remove the lug nuts used to hold the disc and slide the disc from the hub. During installation, place the disc in position over the threaded studs. Install the torque plate, tightening the bolts to the specified torque. Proceed to install the caliper, ensuring the bolts are tightened correctly. Bleeding is not required unless the brake hose was disconnected. Install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque. Depress the brake pedal a few times to bring the brake pads into contact with the disc. Before driving the vehicle, carefully check the operation of the brakes.
