Passenger Vehicle Brake Faults - Effects on Handling, Prevalence, and Criteria for Detection

The results of an investigation of the relationship between course deviation and quantified brake faults are presented in this paper. The development of chassis dynamometer brake testing criteria, correlated with road test and physical inspection results, is discussed. Statistics on the prevalence of in-use vehicle brake system faults are given. The improvements in perception and repeatability enabled by computer automation of the dynamometer brake tester are described.
