- Content
- 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 five test units designated A, B, C, D, and E are to be used to perform all tests per 1.1 and 1.2.
- Content
- New changes addressed requests to increase the Salt Spray Requirements, add Vacuum Requirements to Boot Seal Validation, allow longer pressure stabilization times during leak testing, add allowable cooling time between mechanical release test cycles, allow optional 5 Gallon Air Tank reservoir for pressure decay leak testing, standardize incremental measurements to 5 mm (0.20 in), and add Arctic temperature Leakage and Operational testing to allow the SAE J1450 specification to be suspended or cancelled.
