Air Brake Actuator Test Performance Requirements - Truck and Bus
This procedure provides test performance requirements for service, spring applied parking, and double diaphragm
combination air brake actuators with respect to durability, function, and environmental performance when tested in
accordance to SAE J1469.
Rationale: The minimum pressure response is too sensitive to the size of the chamber to define a recommended range that can be
applied for all sizes. The minimum pressure response recommended range was removed. The minimum pressure
response is to be measured and recorded and made available upon customer request.
