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.
Updated to be consistent with SAE J2932 (Disc Brake), aligned sections to match SAE J1469. Parking force requirements redefined to be consistent with service force requirements, from 33% to 90% of rated stroke. Added 130psig Force Output – Service Chamber requirement.
