Past research has shown the stopping performance of vehicles equipped with air brake systems to be very dependent on brake adjustment. The Commercial Vehicle Safety Alliance (CVSA) and the Federal Highway Administration's Office of Motor Carrier Standards (OMCS) have recognized this fact and adopted brake adjustment inspection criteria for placing motor vehicles out of service. The report describes tests to investigate the effect of brake adjustment on braking performance by means of stopping distance tests on one single-unit truck and two tractor/trailer combinations, brake dynamometer tests and computer simulation. Descriptions of the vehicles, test site, and test procedures are given along with discussions of the test and simulation results. The test results can serve as the basis for evaluating the appropriateness of the current out-of-service criteria for brake adjustment with regard to vehicle safety.
