Abstract:
A method for automatically adjusting the alignment between a vehicle brake assembly and an on-vehicle brake lathe having a lathe body with a driving motor, a cutting head operably attached to the lathe body, and a drive shafts wherein the on-vehicle brake lathe is operably attached to the hub of the vehicle brake assembly to compensate for runout, the method comprising the steps of:(a) measuring movement of the lathe body;(b) electronically comparing the measured movement of the lathe body with a stored acceptable limit and ceasing further adjustment if the measured movement is below the stored acceptable limit;(c) automatically adjusting in a first direction a relative axial position of the lathe drive shaft with respect to an axis of rotation of the vehicle brake assembly;(d) repeating measuring step (a), and, if the measured movement has decreased, repeating steps (a) and (c) until the measured movement increases;(e) automatically adjusting in a second direction the relative axial position of the lathe drive shaft with respect to the axis of rotation of the vehicle brake assembly;(f) repeating measuring step (a), and, if the measured movement has decreased, repeating steps (a) and (e) until the measured movement increases.
