Abstract
A clutch device for a clutch system has a nose cap and a piston that is movable in an axial direction with respect to the nose cap. A seal disposed in the axial direction between the nose cap and the piston automatically locks the clutch device when a threshold amount of wear has accrued in a friction interface of the clutch device. If the seal is not compressed in the axial direction, then a pressurized fluid can flow past the seal and the piston is displaced in the axial direction away from the nose cap. If the seal is compressed in the axial direction, then the pressurized fluid does not flow past the seal and the piston is not displaced in the axial direction away from the nose cap.
