The study discusses the need for regulatory agencies, vehicle manufacturers and brake suppliers to incorporate (vastly) improved braking technology in commercial motor vehicle designs. To help meet this need, the National Transportation Safety Board recommends that Federal funds be made available to design, build and test an Experimental Safety Vehicle--Truck Brake. Commercial vehicle braking requirements are discussed in relation to the need for a systems analysis approach to reduce the braking incompatibility of passenger cars and commercial vehicles. Weaknesses of air brake systems are reviewed to illustrate the futility of efforts to improve existing systems. The need for faster acting and properly timed application systems, coupled with the marginal energy-absorption capability of the foundation brake and the inherent variables resulting from differences in tire-to-road unit loads are advanced as arguments to support a new approach to the overall problem. The study suggests that consideration be given to incorporating hydraulically actuated, anti-skid, disc-type brakes with a supplemental energy absorption system in commercial vehicle brake designs.
