Various examples of brake actuators are provided. In one example, a brake actuator includes a parking brake chamber defined by a spring housing and an adapter base. The parking brake chamber includes a parking diaphragm that has an opening and the parking diaphragm is disposed between the spring housing and the adapter base which divides the brake spring chamber into a spring volume and a release volume, with the spring volume of the brake spring chamber being sealed from atmosphere. The parking brake chamber also includes a piston that is disposed in the spring volume and is in contact with the parking diaphragm, and the piston includes a piston passageway through the piston to allow air flow between the release volume and the spring volume.
