ABSTRACT:
Brake actuators are provided with self-centering diaphragms. In one embodiment, the diaphragm is provided with a centering bead radially outwardly of a sealing bead. The centering bead ensures the diaphragm is properly centered prior to the brake actuator housings being secured together. In a second embodiment, the self-centering structure includes structure fit into mating structure in one of the brake actuator housings to ensure the diaphragm is properly centered. The self-centering structure ensures the brake actuator diaphragms are properly centered before connection of the two brake actuator housings. This invention is particularly useful in the type of brake actuator housings having deformed housing portions.
