Brake out-of-service rate up

During Operation Air Brake Safety Week, the number of out-of-service defects for both brake adjustment and brake components are down slightly, while the overall OOS rate for brakes increased, the Commercial Vehicle Safety Alliance announced.

“Brakes continue to be the number one OOS defect and Brake Safety Week is a reminder of the critical importance they serve in the safe operation of commercial vehicles,” said Stephen A. Keppler, CVSA’s executive director.

Overall results show:

  • Record 30,872 vehicles inspected Sept. 11-17. This exceeds the 2010 mark of 30,472 vehicles, the previous record inspected.
  • 2,605, or 8.4 percent, of vehicles were placed OOS for brake adjustment, compared with 8.9 percent in 2010.
  • 2,453, or 7.9 percent, of vehicles were placed OOS for brake components, down from 8 percent in 2010.
  • 4,385, or 14.2 percent, of vehicles were placed OOS for brakes overall, up from 13.5 percent in 2010.

This year the OOS rates for Canada were again lower than in the U.S. This year 8.7 percent of vehicles inspected in the U.S. during Brake Safety Week were placed OOS for poor brake adjustment, compared with 3.7 percent in Canada. Inspections in Canada resulted in 7.3% of vehicles being placed out of service for brakes, compared with 4.4 percent in 2010.
