Inspectors from Canada, Mexico, and the U.S. conducted 4,898 inspections of commercial motor vehicles in an unannounced special event on April 30. 570 vehicles were taken out of service due to critical violations.

In a press release, the Commercial Vehicle Safety Alliance stated that more than 88% (or 88%) of those vehicles passed inspection without any violations.

Each year, CVSA law enforcement jurisdictions are invited to participate in a one-day, unannounced brake-safety inspection and regulatory-compliance enforcement event. On this day, CVSA-certified commercial vehicle inspectors will conduct their routine roadside checks with a focus primarily on brake systems and components. They will then provide inspection and violation data relating to brakes and brake systems.

This year, 4,328 motor vehicles passed the inspections without any brake-related out of service violations. 570 vehicles, however, were found driving on roads with critical violations. These vehicles were immediately prohibited from traveling until the violations were addressed.

CVSA’s Brake Safety Day, which was not announced, is part of Operation Airbrake. This CVSA program is aimed at improving brake safety in commercial motor vehicles throughout North America. CVSA’s Brake Security Week, a second Operation Airbrake initiative, is scheduled from Aug. 25 to 31.

Inspectors identified 330 commercial vehicles with a 20% brake violation. This means that 20% or more of a vehicle’s service brakes (or combining vehicles) were out of service, resulting in faulty brakes. This was the most common Brake Safety Day violation. It accounted for 57.9% out-of service brake violations.

Inspectors found that 256 (44,9%) of the commercial vehicles inspected had other brake violations. Other brake violations include broken brake drums, worn brake lines/hoses or inoperative tractor protection systems, low-air warning devices that are not working, air leaks, and hydraulic fluid leaks.

A total of 73 commercial vehicles had steering-related violations of brakes — 12.8% of the brake-related out of service violations.

The inspections this year focused on brake violations, including:

Inspectors found that 108 power units, and 66 tow units had lining/pad violations.

* There were 114 brake lining/pad violations and 48 violations for contamination on power units.

On towed units, 71 brake lining/pad violations were found. Twenty-three violations were due to cracks/voids within the brake linings/pads, the most common brake lining/pad violation found on towed vehicles.

* Eighty-eight performance-based-brake-tester-inspections were conducted at nine U.S. jurisdictions on Brake Safety Day. Four (4.5%) failed to meet the 43.5% braking efficiency minimum required and were taken out of service.

Operation Airbrake aims to reduce the number highway crashes caused due to faulty brake systems on commercial motor vehicles. This is done by roadside inspections as well as by educating drivers, mechanics and owner-operators on the importance of proper inspection, maintenance and use of brakes.

The combined number of out-of service violations for commercial motor vehicles is half due to brake system and out-of adjustment brakes. Incorrectly installed or poorly maintained brake systems can reduce the braking capability and stopping distance of commercial motor vehicles.
