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.

Truck and Bus Brake Actuator Committee
The Truck and Bus Brake Actuator Committee of the Truck and Bus Brake and Advanced Driver Assistance Systems Steering Committee is responsible for developing, reviewing, and approving recommended practices, standards, and information reports related to air brake actuators and their interfacing as used on trucks, tractor-trailer combinations and buses over 10,000 lbs (4500 Kg) GVWR designed primarily for highway use.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
