The program determined the effects of selected modes of disc- and drum-brake component degradation on vehicle braking performance. The results are used to recommend brake-component and system-performance limits of degradation. In this program an inertial brake dynamometer was used to evaluate physically the effects of thin friction materials, friction-material wear characteristics, effects of friction material contamination, and the effects of heat spots, rotor scoring, out-of-round drums and disc lateral runout. Also physically evaluated were sticky wheel cylinders. The other major tasks were the evaluation of side-to-side brake imbalance with vehicle-handling models and vehicle test conducted with sample drivers and the analytical determination of inspection criteria for brake system proportioning (front-to-rear ratio) and brake pedal reserve.
