A pneumatic brake for a vehicle is provided. The pneumatic brake includes a housing and a single diaphragm within the housing that divides the housing into front and rear variable-volume chambers. A push rod is disposed in the front chamber and extends outwardly from the housing. A parking spring is disposed in the rear chamber and urges the diaphragm and push rod towards the front chamber. A valve body extends through the rear chamber and includes an elongated stem disposed in a telescoping relationship with the push rod. In resting and activation modes, brake pressure is applied by the parking spring to the top plate to activate a brake function. In a deactivation mode, pneumatic pressure is supplied to the front chamber to compress the parking spring and disengage the brake. A brake system including the pneumatic brake and an ABS is also provided.
