Abstract
A soft-release lever-operated control system for parking brake cables is disclosed including a helical main clutch spring arrangement permitting movement of the operating lever only toward the brake-engaged position, and a release device for releasing the main clutch spring to permit return of the operating lever toward the brake-released position. According to another embodiment of the invention, a second helical clutch spring arrangement is provided that is activated when the operating cable is returned to the brake-released position, thereby to activate a cable tension adjusting device that removes slack contained in the inner brake cable operating member. According to a further embodiment, a push-to-release arrangement including a toggle pawl and spring device is operable upon tapping of the operating lever to place the system in a brake-released condition.
