The procedure is to clean any rust or corrosion from the mating surface of the hub/axle flange and any rust or corrosion from the mating surface and mounting surface of the brake rotor, inspect the mating surfaces of the hub/axle flange and the rotor, mount the brake rotor to the brake lathe, slowly bring in the cutting tools until they just contact the brake rotor friction surfaces, observe the witness mark on the brake rotor, refinish the brake rotor, inspect the brake rotor thickness, follow the brake lathe manufacturer's recommended speed setting for applying a non-directional finish, apply the non-directional finish, clean each friction surface of the brake rotor with denatured alcohol, or an equivalent approved brake cleaner, remove the brake rotor from the brake lathe, and then measure the assembled LRO of the brake rotor to ensure optimum performance of the disc brakes.
