The Bendix Spring Brake combines a service brake chamber with a parking spring mechanism for trucks running S-cam foundation brakes. One actuator handles three jobs, providing service braking, parking, and emergency braking depending on how the vehicle is piped. Inside the Bendix K151052, diaphragms made from natural rubber over a nylon fabric layer turn air pressure into pushrod force. Because the parking section holds a loaded compression spring, the crimped band on the spring chamber is never meant to be opened in service.
