Scope
Content
This Recommended Practice is derived from the Federal Motor Vehicle Safety Standard 135 vehicle test protocol as a single-ended inertia-dynamometer test procedure. It measures brake output, friction material effectiveness, and corner performance in a controlled and repeatable environment. The test procedure also includes optional sections for parking brake output performance for rear brakes. It is applicable to brake corners from vehicles covered by the FMVSS 135 when using the appropriate brake hardware and test parameters. This procedure is applicable to all passenger cars and light trucks up to 3500 kg of GVWR.
Rationale
Content
This Recommended Practice is the result of an industry effort to develop an inertia-dynamometer test procedure based upon the FMVSS 135 vehicle test. Results from this test provide a laboratory assessment of the brake corner performance. Data from this Recommended Practice may be combined with other brake system and vehicle characteristics to predict vehicle performance.
The conditions defined in this Recommended Practice are drawn from FMVSS 135 vehicle test experience. The deceleration levels are not necessarily based on those needed to meet the requirements of the FMVSS 135. This procedure is intended to properly represent the lining conditioning which occurs during an FMVSS 135 vehicle test.
