Abstract
A power door lock actuator includes a one piece molded and centrifugally expandable brake ring that is held on a drive ring to a motor shaft within a lock lift arm driving cup that is freely pivoted to the shaft. A camming member on the drive ring fits within the brake ring so as to retain it to the shaft, to maintain it in a ready position spaced from the cup when stationary, and so as to jam it into the wall of the cup when turning.
