Abstract
A brake actuator system of a vehicle comprising a diaphragm design with a hole and sealing element in the center. The design allows for the sealing element to seal and slide on the outer diameter of the center pushrod for the exposed length. This eliminates the need for a fixed joint to permanently attach the diaphragm to the center pushrod, and allows for the pushrod to be attached to the spring piston or a separate fixed plate and reduces stress of the diaphragm at its interface.
