GREENBELT, Md. — An unannounced brake check day held by the Commercial Vehicle Safety Alliance (CVSA) in the US and Canada May 6 as part of Operation Airbrake placed 14.2% of inspected units out of service as a result of brake issues.
That’s down a point from last year’s 15.2% OOS rate.
In Canada, however, only 10.3% of trucks inspected were placed out-of-service, with Ontario recording the lowest rate at 7.3%. The US fared worse, with 15.9% of inspected trucks placed out of service with brake issues.
Thirty-two states and provinces participated in the brake blitz. A total of 6,337 commercial motor vehicles and more than 50,000 individual wheel-ends were inspected. In Canada, 4% of inspected units were placed out of service due to incorrect brake adjustments, while in the US the number was 11.3%.
CVSA found brakes with manual adjusters were 2.5 times more likely to be out of adjustment than those equipped with self-adjusting brake adjusters.
