Disc brake rotors on driven axles are resurfaced without being removed from host axles by replacing the relatively non-abrasive service brake pads with abrasive grinding pads. Grinding pads are urged into contact with the rotor being resurfaced utilizing the service brake piston. The rotor to be resurfaced is driven by the vehicle drive train after the vehicle has been raised to prevent wheel contact with the ground.
