The Commercial Vehicle Safety Alliance (CVSA) has set September 7, 2017, as Brake Safety Day where inspections of trucks will occur throughout North America.
According to the CVSA, Brake Safety Day inspectors will primarily conduct the North American Standard Level I Inspection, which is a 37-step procedure that includes an examination of both driver operating requirements and vehicle mechanical fitness.
Brake inspections will look for things like (but are not limited to):
In the 10 jurisdictions using performance-based brake testing (PBBT) equipment, vehicle braking efficiency will be measured. PBBT systems include a slow speed roller dynamometer that measures total vehicle weight and total brake force from which braking efficiency is determined, says the CVSA.
The minimum braking efficiency for trucks is 43.5 percent, required by U.S. federal regulation and the CVSA out-of-service criteria.
From September 11-17 2016, the CVSA conducted a Brake Safety Week with inspectors reporting 13.2 percent of inspections resulting in out-of-service brake violations and 14.8 percent of inspections with non-brake related out-of-service violations.
During the 2016 International Roadcheck brake-related violations were responsible for 45.7 percent of all out-of-service violations, the largest percentage of any violation.
