Brake adjustment area of concern during CVSA’S Brake Safety Week


More than 50 percent of commercial motor vehicle (CMV) out-of-service violations cited during roadside inspections were for brake-related violations, according to Commercial Vehicle Safety Alliance (CVSA) Roadcheck 2011 data, indicating much more education and awareness is needed to reduce the number of highway crashes caused each year by poorly maintained braking systems on commercial vehicles.

CVSA is working with drivers, mechanics and others during the week of September 11-17, 2011, Brake Safety Week, to enhance knowledge, regulatory compliance and performance of CMV braking systems.

An international not-for-profit organization comprised of local, state, provincial, territorial and federal motor carrier safety officials and industry representatives from the United States, Canada and Mexico, CVSA’s Our mission is to promote commercial motor vehicle safety and security by providing leadership to enforcement, industry and policy makers

“Ultimately, brakes are a major factor in being able to operate a commercial vehicle safely, yet they continue to be cited as one of the leading factors in crashes due to defects and improper maintenance and adjustment,” said Stephen A. Keppler, CVSA’s executive director. “One of the major goals of Brake Safety Week is to educate drivers, mechanics and others on the importance of proper adjustment, maintenance, and operation to ensure every commercial vehicle is operating safely, and, ultimately, to save lives.”

During Brake Safety Week CVSA-Certified Inspectors, brake suppliers and industry partners conduct enforcement and education activities with drivers and mechanics at truck stops, weigh stations and other locations.

This week-long campaign is part of the ongoing CVSA effort, called Operation Air Brake, dedicated to improving inspection, compliance, maintenance, and performance of commercial vehicle braking systems throughout North America. It is conducted with, and supported in part by the Federal Motor Carrier Safety Administration (FMCSA).

“FMCSA’s strong partnership with law enforcement nationwide is about raising the bar for safer trucks and buses.  To do that, FMCSA proudly joins with our state law enforcement partners to conduct Brake Safety Week," said FMCSA Administrator Anne S. Ferro.

During Brake Safety Week in addition to conducting roadside inspections, enforcement will be deploying Performance-Based Brake Testers in several participating jurisdictions and at a number of inspection locations.

During the course of this year, as part of Operation Air Brake, CVSA developed two portable brake adjustment demonstration models that have been used throughout the year at industry events to demonstrate and illustrate the importance of proper brake adjustment. 

There are many other educational components that are part of the Operation Air Brake Campaign, to include a web-based training program geared toward drivers and technicians, as well as instructional guides and handbooks. The campaign exists principally to reduce the out-of-service rate for brake-related defects.

This Selective Traffic Enforcement Program (STEP) model has been used successfully in other areas of traffic safety concerns (most notably seat belt usage), and is being employed throughout North America to focus on the very important issue of brake safety and regulatory compliance. It was developed and initiated by Canada in 1998.
