Lexus 35682-33010 Disc, Brake, NO.2

Begin by loosening the wheel lug nuts. Then, raise the vehicle and securely support it on jackstands. Remove the wheel and install the lug nuts to hold the disc in place. If you're working on the rear brake disc, ensure that the parking brake is released.

To check disc runout, use a dial indicator positioned approximately 1/2-inch from the outer edge of the disc. Set the indicator to zero and turn the disc, ensuring that the reading remains within the specified allowable runout limit. If it exceeds this limit, the disc will need refinishing at an automotive machine shop. Professionals often recommend replacing the discs whenever replacing the pads, regardless of the dial indicator reading, to achieve a smooth finish and ensure a perfectly flat surface.
