Book Description
This report presents analyses, findings and recommendations concerning the brake adjustment criteria of the North American Uniform Driver-Vehicle Inspection Criteria for heavy trucks. The study involved interviews with Motor Carrier Safety Assistance Program (MCSAP) inspectors, mechanical analyses of the influence of brake adjustment on stopping capability, statistical analyses of brake inspection data, combined statistical and mechanical analyses of the current brake adjustment criteria, and development of a procedure for estimating or predicting brake adjustment intervals. The key statistical results are derived primarily from a set of 2,146 brake inspections performed by the National Transportation Safety Board. The data indicate 936 of the 2,146 vehicles (with S-cam brakes) were placed out of service for brake adjustment. Of the 936 vehicles placed out of service, 480 vehicles had braking capability that was greater than 80 percent of what the braking capability would have been if the brakes were fully adjusted. These 480 vehicles represent "false positive" cases. The study presents recommendations for changes to the brake adjustment criteria in order to reduce the percentage of "false positives" during roadside inspections and a procedure motor carriers can use to estimate brake adjustment intervals.

Book Description
The increase in forest road grades has resulted in safety concerns for log hauling operations. FPInnovations developed guidelines to assist road planners and operational staff in safely operating on steep grades. Studies have shown that properly functioning service brakes are critical when operating on steep grades. Other studies have consistently identified truck air brake adjustment to be a major contributing factor to the out-of-service rate of the trucks, and despite the prevalence of automatic slack-adjusters, brake adjustment continues to be an issue. A study conducted by the Insurance Corporation of British Columbia (ICBC) in 1998 recommended the need for low cost in-cab brake monitoring device on trucks to provide feedback to drivers. To this end, a manufacturer (GeoGuidance Corporation) was identified which had developed a brake monitoring system potentially suitable for harsh operating environments such as log-hauling.
