The Commercial Vehicle Safety Alliance (CVSA) today announced the date of this year’s Brake Safety Week campaign.

The annual enforcement blitz will run September 6-12, 2015.

Brake Safety Week is a nationwide campaign sponsored by the CVSA, in partnership with the U.S. Department of Transportation. Throughout North America, commercial vehicle inspectors will be out in full force conducting Level 4 inspections. Defective or out-of-adjustment brakes will result in the vehicle being placed out of service.

“Brake inspections conducted during Brake Safety Week include inspection of brake-system components to identify loose or missing parts, air or hydraulic fluid leaks, worn linings, pads, drums or rotors, and other faulty brake-system components. Antilock braking system (ABS) malfunction indicator lamps also are checked. Inspectors will inspect brake components and measure pushrod stroke where applicable. Defective or out-of-adjustment brakes will result in the vehicle being placed out of service,” CVSA states.

In addition, some Level I inspections will be conducted in the 10 jurisdictions that are currently using performance-based brake testing equipment, the CVSA warns. “The minimum braking efficiency for trucks is 43.5 percent, required by U.S. federal regulation and the CVSA Out-of-Service Criteria.”
