Scope
This SAE Recommended Practice provides procedures and methods for testing service, spring applied parking, and combination brake actuators with respect to durability, function, and environmental performance. A minimum of six test units designated A, B, C, D, E, and F are to be used to perform all tests per 1.1 and 1.2.
Rationale
This revision adds a test unit âFâ for corrosion testing which allows future reference to SAE J2721. Made optional the parking volume reporting. Added high pressure service side cycles as prep for current cycle testing. Added requirements to read and record SAE J2899 rated stroke marking after corrosion test. Reorganized test order such that proof pressure is done at the end of test. Reorganized test order such that volume testing is done after low temperature testing. Made optional the minimum pressure response. Removed Disc Brake sections as it has been moved to SAE J2902. Made optional the low temperature parking force and hold-off. Made artic leak an alternative test procedure. Added 130 psig pressure test condition to Force output â Service Chamber.

* 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.
