This document is derived from the Federal Motor Vehicle Safety Standards 105 and 135 vehicle test protocols as single-ended inertia-dynamometer test procedures. It measures brake output, friction material effectiveness, and corner performance in a controlled and repeatable environment. The test procedures also include optional sections for parking brake output performance for rear brakes. It is applicable to brake corners from vehicles covered by the FMVSS 105 and 135 when using the appropriate brake hardware and test parameters. The FMVSS 135 is applicable to all passenger cars and light trucks up to 3500 kg of GVWR. The FMVSS 105 is applicable to all passenger cars, multi-purpose vehicles, buses, and trucks above 3500 kg of GVWR. This document does not include testing for school bus applications or vehicles equipped with hydraulic brakes with a GVWR above 4540 kg. This Recommended Practice is the result of an industry effort to develop inertia-dynamometer test procedures based upon the FMVSS 105 and 135 vehicle tests. Results from these tests provide a laboratory assessment of the brake corner performance. Data from this document may be combined with other brake system and vehicle characteristics to predict vehicle performance. The conditions defined in this document are drawn from FMVSS 105 or 135 vehicle test experience. The deceleration levels are not necessarily based on those needed to meet the requirements of the FMVSS. These procedures are intended to properly represent the lining conditioning which occurs during an FMVSS vehicle test. This revised document includes test procedures for vehicles below 4540 kg of Gross Vehicle Weight Rating. FMVSS 135 test procedure is covered by Section 8.1 and Table 2. FMVSS 105 test procedure is covered by Section 8.2 and Table 3. The different items, definitions, and sections indicate clearly whenever it applies only to the FMVSS 105 or the FMVSS 135 test procedure.
