In a brake actuator including a plurality of actuator housing portions, a diaphragm seal, partially delimiting a parking brake de-actuation chamber, is retained between adjacent actuator housing portions, and an elastic element disposed between the diaphragm seal and one of the housing portions opposes expansion of the parking brake de-actuation chamber. A push rod extends into and out of a service brake actuation chamber upon respective release of fluid pressure from the parking brake de-actuation chamber and supply of fluid pressure to the parking brake de-actuation chamber. In order to constrain a central portion of the diaphragm seal for movement together with both the push rod and a piston, a clamping arrangement is used to axially clamp the central diaphragm seal portion between an end of the push rod and a surface of the piston.
