Brake System Design for Medium/Heavy Trucks to Meet FMVSS 105-75 Stopping Distance Requirements

A practical method has been devised to size foundation brakes to meet the stopping distance requirements as specified in FMVSS 105-75, Notice 11. Also, a technique has been created to statistically predict the stopping performance of a vehicle as well as the probability of meeting a specified stopping distance criteria. This paper also summarizes the development of Bendix' disc brakes which not only exceed the torque requirements necessitated by federal legislation, but also demonstrate improved life and handling characteristics as compared to competitive designs.
