Six vehicles were tested to Motor Vehicle Safety Standard No. 105-75, Hydraulic Brake Systems, to determine the degree to which their performance complied with the requirements of that standard. The vehicle group included a compact pickup truck, a large 4x4 pickup truck, a small 4x4 and large 4x4 multi-purpose vehicle, and two delivery van trucks. Although the standard presently does not apply to any of the vehicles tested, information was desired on their ability to meet the performance requirements of the standard. All of the vehicles were manufactured in the 1978 model year. Braking performance data for stops made on a wet surface are also included. In addition to the performance testing required in the FMVSS 105-75 test procedure, a series of special tests were conducted of vehicle braking on several surfaces ranging widely in skid number to determine the relative correlation of stopping distance with peak and slide friction coefficients measured for each surface. This report presents a description of the test program and an analysis of the results. It includes: descriptions of vehicles, instrumentation, and test site; detailed data sheets, vehicle performance summaries and graphs; surface friction - stopping distance correlation data; and a discussion of results.
