This Recommended Practice applies to on-road vehicles with a GVWR below 4540 kg equipped with disc brakes.

This Recommended Practice applies to on-road vehicles with a GVWR below 4540 kg equipped with disc brakes.

This SAE Recommended Practice describes two methods for installing thermocouples in automotive brake discs or drums for the purpose of indicating bulk temperature during inertia dynamometer and vehicle road tests.

This document derives from the Federal Motor Vehicle Safety Standards 105 and 135 vehicle test protocols as single-ended inertia-dynamometer test procedures. The test sequences enable brake output measurement, friction material effectiveness, and corner performance in a controlled and repeatable environment. This SAE Recommended Practice (RP) also includes optional sections for parking brake output performance for rear brakes. It applies to brake corners from vehicles covered by the FMVSS 105 and 135 when using the appropriate brake hardware and test parameters. The FMVSS 135 applies to all passenger cars and light trucks up to 3500 kg of GVWR. The FMVSS 105 applies 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 procedure provides methods to determine the appropriate inertia values for all passenger cars and light trucks up to 4540 kg of GVWR. For the same vehicle application and axle (front or rear), different tests sections or brake applications may use different inertia values to reflect the duty-cycle and loading conditions indicated on the specific test.
