DRAULIC/MECHANICAL/ROTORS - STANDARD PROCEDURE) STANDARD PROCEDURE - BRAKE ROTOR NOTE: Refacing the rotor is not required each time Any servicing of the rotor requires extreme care to maintain the rotor within service tolerances to If the rotor surface is deeply scored or warped, or there is a complaint of brake roughness or brake on-car brake lathe (Fig. 62), or replaced. The use of a hub-mounted on-car brake lathe is highly recommended to eliminate the possibility of NOTE: All rotors have markings for minimum allow- thickness specifications can also be found in the specification table in this section. Minimum allowable thickness is the minimum thickness which the brake rotor machined surface CAUTION: Do not machine the rotor if it will cause Before lathe installation, verify the brake rotor face and the hub adapters are free of any chips, rust, When mounting and using the brake lathe, strict attention to the brake lathe manufacturer’s operating Machine both sides of the brake rotor at the same time. Cutting both sides at the same time minimizes When refacing a rotor, the required TIR (Total Indicator Reading) and thickness variation limits sections specification table.
