Abstract
A movable barrier operator release mechanism includes an operator chassis having a first side. A shaft extending in a first direction from the first side of the chassis. A brake assembly coupled to the chassis and the first shaft extends into the brake assembly. The brake assembly includes a lever, mounted to a mounting plate of the brake assembly on end and freely movable at the other end. A cable attached to the lever that when pulled pivots the lever about its mounting point. When moved, the lever disengages the brake assembly allowing for free movement of the movable barrier.
