BRAKE CHAMBER TYPE 30

A Type 30 brake chamber is a pneumatic actuator used in heavy-duty air brake systems. It converts compressed air into mechanical force to apply the brakes when the pedal is pressed. This size is commonly found on drive axles and trailer axles. Replacement is necessary when the chamber develops air leaks, the internal diaphragm tears, or the push rod stroke exceeds the legal adjustment limit, which can lead to reduced braking performance or safety violations.
