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. The system calculates the appropriate rotational position for each slant disc within the aligning joint required to impart a necessary adjustment in the wheel coupling rotational axis in order to align the on-car brake lathe with the rotational axis of the wheel hub. Finally, an adjustment mechanism is activated to rotationally drive each slant disc directly to the calculated rotational position with a minimum amount of rotational movement based on the current rotational position of each slant disc and the required calculated rotational positions.

An on-vehicle disk brake lathe system is attachable to a vehicle in order to machine a brake disk attached to a wheel hub and rotating about a wheel hub axis. The brake disk has an in-board friction face and an out-board friction face opposite the in-board friction face. The on-vehicle disk brake lathe system comprises a cutting mechanism and a brake disk drive unit including a wheel hub adaptor removably connectable to the wheel hub and a motor configured to rotate the wheel hub adaptor and the brake disk when the wheel hub adaptor is connected to the wheel hub. Further, the on-vehicle disk brake lathe system comprises a capture device. The capture device is configured to be moved to a position at which the capture device can capture an image showing at least a portion of the brake disk and/or at least a portion of the cutting mechanism.

An adjustable hub adapter for coupling an on-car brake lathe to a wheel hub. An annular support frame coaxially carries an axially bored and threaded central mounting hub with a set of equidistantly spaced spokes. A lug bolt receiver is associated with each spoke, and consists of a receiving tube, a lever arm pivotally coupled to the spoke at a pivot bolt in proximity to the annular support frame. An engagement pin on each lever arm is captured within a synchronizing ring carried on the annular support frame. The rotational movement of any lug bolt receiver about an axis of the pivot bolt imparts rotational movement to the synchronizing ring, and in turn, causes each remaining bolt receiver to rotate about an associated pivot bolt axis, maintaining the lug bolt receivers in a synchronized and symmetric radial displacement from the central mounting hub.

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.
