Scope
This SAE Recommended Practice establishes a uniform laboratory procedure for evaluating performance and wear of automotive brakes and brake drums by an inertial dynamometer simulation of vehicle test and operating conditions. The code is applicable to hydraulic, air, or electrically actuated brakes. For electric brakes, 'ampere' values are substituted for 'line pressure' where specified in the procedure or on data and curve sheets. The procedure includes the following tests: 1. Torque output and deceleration (various speeds and brake input). 2. Evaluation of lining life (wear tests). 3. Brake characteristics (fade and recovery tests, noise, chatter, grabbiness). 4. Drum evaluation (wear, heat checking, scoring).

Brake Dynamometer Standards Committee
The Brake Dynamometer Standards Committee is part of the Foundation Brake Steering Committee that reports to the Motor Vehicle Council. The committee is responsible for developing standards, recommended practices, and information reports for brake dynamometer testing, for on-road vehicles below 4540 kg of Gross Vehicle Weight Rating. The committee also maintains liaison activities with other Standard Development Organizations or industry consortia.

* 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.
