This paper presents an overview of the main test
protocols used by the friction industry to assess
performance. Brake performance primarily measures
stopping distance, brake output torque, or effectiveness
(also referred as friction level or BEF for drum brakes).
The two main types of tests used to evaluate
performance under different loading, speed, temperature
and pedal force/brake pressure are vehicle-level and
inertia-dynamometer testing. The paper presents the
main test protocols along with key sections of the test
report, typical test conditions, and test equipment used
for: passenger cars, Sport Utility Vehicle —SUV, light
duty trucks, and commercial vehicles. The main test
procedures, publicly available, for this purpose are:
