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:
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.
Affected tractors are equipped with an automated Eaton UltraShift Plus or Eaton Advantage Transmission with right hand stalk shifter. In the affected trucks, the display on the instrument panel can indicate “N” when the shifter is set into “D” or “R,” causing the truck not to move.
