Abstract
An on-car brake lathe is provided with a runout compensation system configured to monitor the rotational position of a pair of slant discs within an aligning joint of the on-car brake lathe. The system monitors the amount of runout present between the rotating components of the on-car brake lathe and the wheel hub to which the on-car brake lathe is secured, and calculates a relative rotational position for each slant disc within the aligning joint required to impart a necessary adjustment in the wheel coupling rotational axis to align the on-car brake lathe with the rotational axis of the wheel hub. An adjustment mechanism within the aligning joint is configured to rotationally drive each slant disc to the calculated relative rotational positions with a minimum amount of rotational movement based on the current relative rotational position of each slant disc and the required calculated relative rotational positions.
