  • Self adjusting parking brake
    Patent number: 4440269
    Abstract: The parking brake cable is loaded and then maintained at a substantially constant tension force existing while the parking brake is not applied. This tension force maintains the parking brake in adjustment, permitting initiation of parking brake application with an increase in cable tension force which minimizes lost movement of the parking brake control mechanism to move the brake shoes into friction contact with friction braking surfaces.
