The differential brake system including a frame fixedly mounted with respect to the shafts and a brake assembly mounted on the frame for connecting the shafts to the frame. The brake assembly and clutch assembly each including a set of plates and a set of discs which are selectively actuated by an actuator plate mounted on the frame. The actuator plate is positioned to move a thrust bearing into engagement with the clutch assembly in one direction of motion and a brake ring into engagement with the brake assembly in the other direction of motion. A compensating assembly is provided for compensating for wear of the clutch plate assembly.
