Patent ID: 7270037

Claim:
A method of resurfacing a brake disc of a vehicle brake assembly including a hub using a brake lathe system that includes a lathe body, at least one cutting head operably attached to the lathe body, and an alignment mechanism comprising a sensor, an alignment adjustment mechanism operable to align the lathe body of the brake lathe system with, a vehicle, and a microprocessor coupled to the sensor, the method comprising: attaching an on-vehicle brake lathe system to the hub of the vehicle brake assembly; using the sensor, generating a measurement signal indicative of the orientation of a lathe axis of rotation with respect to a rotor axis of rotation; using the microprocessor, electronically generating at least one control signal in response to the measurement signal; adjusting the orientation of the lathe axis of rotation with respect to the rotor axis of rotation using the alignment mechanism and in response to the at least one control signal so as to improve the alignment of the lathe axis of rotation with respect to the rotor axis of rotation; and rotating the hub of the vehicle brake assembly with respect to a lathe cutting head to resurface the brake disc of a vehicle brake assembly.
