ABSTRACT:
A spring acts on an operating member of a parking brake control and, when the brake is released, not only reduces the flyback energy resulting from the release but also stores such energy for use as a power assist during the next application of the brake. The spring acts on the operating member through a cam which removes the spring force from the operating member when the brake is fully released while progressively amplifying the spring force as the brake is progressively applied.
