Abstract
An electrically operated drive assembly for turning a motor vehicle disc brake rotor while the rotor is still on the vehicle includes a portable stand or base having a combination electric motor and adjustable drive shaft assembly pivotally mounted thereon. The end of the drive shaft is selectably releaseably retained on a lug adapter mechanism that is retained on the motor vehicle wheel lugs. The drive shaft assembly includes a right angle bend that allows the entire drive assembly to be positioned to one side of the motor vehicle wheel hub and rotor assembly. This arrangement allows a mechanic to have open access to a separate portable brake lathe which is mountable on the vehicle brake caliper mounting bosses. The drive assembly turns the brake rotors at a predetermined speed which is suitable for combined operation with a portable brake lathe.
