A braking arrangement wherein the amount of braking effected on a moving member is determined by the direction of movement of the braked member. Braking is applied to the member via a brakeshoe which is movably coupled to a lever means. In response to the contacting relation with the moving member, the brakeshoe is positioned along the lever means with respect to the fulcrum of the lever. The position of the brakeshoe with respect to the lever means fulcrum determines the effective braking force transmitted to the moving member.
