The release mechanism is actuable for allowing selective movement of the brake lever. A cable is connected to the release mechanism. The cable is isolated from movement of the brake lever.
Claims28
A park brake comprising:
- a brake lever movable about a pivot;
- a release mechanism associated with the brake lever, the release mechanism actuable for allowing selective movement of the brake lever, the release mechanism including a linkage connected to a pawl plate and brake lever wherein the linkage includes first and second links, the first link attached to the pawl plate at one end and including a common pivot linking the first link to the second link at a second end, the second link coupled to the brake lever and wherein the linkage moves between a starting position with the linkage positioned on a first side relative to a center of the linkage and a cam over position with the linkage positioned on a second opposing side of center for locking and releasing the release mechanism;
- a cable connected to the release mechanism;
- wherein the cable is isolated from movement of the brake lever.
