Abstract
A tread brake unit including a spring actuated compensating mechanism for maintaining the brake unit piston stroke constant. A roller associated with the compensating mechanism is adapted to ride along an operating surface of a lever arm that rotates according to the degree of piston stroke. The profile of this operating surface regulates the roller movement to prevent the stressing of operating springs in the compensating mechanism from exceeding a maximum value corresponding to their fatigue limit.
