Claim:
1. A brake assembly for a work machine having a frame and at least one rotating component, the brake assembly comprising: a wheel attached to and rotating with the at least one rotating component; a traction device surrounding, at least in part, the wheel; a tensioning assembly attached to the frame at a frame attachment point of the tensioning assembly, the tensioning assembly including a lost motion linkage limited by a stop to a limited range of motion with respect to the frame, the lost motion linkage being attached to the traction device at a brake attachment point of the tensioning assembly; and a counterforce assembly attached to the traction device at a brake attachment point of the counterforce assembly, and attached to the frame at a frame attachment point of the counterforce assembly; wherein moving at least a portion of the tensioning assembly in a braking direction with respect to the frame attachment point of the tensioning assembly moves the lost motion linkage toward the stop such that the stop prevents further movement of the lost motion linkage with respect to the frame, the tensioning assembly thereby applying a first tensioning force to the traction device, the first tensioning force being resisted by the counterforce assembly, via the brake attachment point of the counterforce assembly, to impose a braking force on the wheel via the traction device and thereby brake the rotating component; and wherein moving the portion of the tensioning assembly in a release direction with respect to the frame attachment point of the tensioning assembly moves the lost motion linkage away from the stop, the tensioning assembly thereby reducing the first tensioning force to reduce the braking force on the wheel.
