A power driving assembly ( 17 ) serves for rotating a disc brake ( 2 ) being resurfaced by means of a disc brake lathe ( 1 ) mounted onto the caliper mounting brackets ( 3 ) of a vehicle wheel hub assembly ( 4 ). The power driving assembly ( 17 ) comprises a motor ( 18 ) and a shaft ( 19 ) for transmitting the power from the motor ( 18 ) to the disc brake ( 2 ). The shaft is a flexible shaft ( 19 ), which is connected to a gear ( 15 ) of a gearbox ( 15' ), which again is connected to the disc brake ( 2 ). The motor ( 18 ) and the disc brake ( 2 ) can be correctly connected to each other quickly and easily.
