Brake Rotor/Disc: Procedures
BRAKE ROTOR MACHINING
NOTE: Refacing the rotor is not required each time the brake pads are replaced, only when the need is foreseen.
Any servicing of the rotor requires extreme care to maintain the rotor within service tolerances to ensure proper brake action.
If the rotor surface is deeply scored or warped, or there is a complaint of brake roughness or brake pedal pulsation, the rotor should be refaced using a
hub-mounted on-car brake lathe (1), or replaced.
The use of a hub-mounted on-car brake lathe (1) is highly recommended to eliminate the possibility of excessive runout. It trues the brake rotor to the
vehicle's hub and bearing.
Minimum allowable thickness is the minimum thickness which the brake rotor machined surface may be cut to.
CAUTION: Do not machine the rotor if it will cause the rotor to fall below minimum thickness.
NOTE: Most brake rotors (2) have markings for minimum allowable thickness specification cast into an unmachined surface of the rotor or
stamped into the hat section (1). Some brake rotors have the minimum thickness specification located elsewhere. Refer to the following
paragraph. Minimum thickness specifications can also be found in this component's specification table. See: Specifications
