An Analysis and Evaluation of Unconventional Methods of Passenger Car Braking

A wide variety of devices which might be used to provide passenger car braking are analyzed. Devices based on reaction principles as well as those involving forces between the car and the road are evaluated from the standpoint of their performance characteristics and their size and weight. It is concluded that none of the methods or devices considered appears useful for general braking applications, but that some may serve as auxiliary braking means or for special applications.
