Air Disc Brake Actuator Test Procedure, Truck-Tractor, Bus and Trailer
This SAE recommended practice provides procedures and methods for testing service, spring applied parking and combination brake actuators for air disc brake applications. Methods and recommended samples for testing durability, function and environmental performance are listed in 1.1 and 1.2.
This new document has been created to separate the testing for air disc brake actuators from the s-cam drum brake actuator testing outlined in SAE J1469. The air disc brake actuators are similar and do require most of the same testing as the s-cam drum brake actuators but do require some different tests. It is anticipated that development of new testing could take a different direction in some cases.
