CVSA publishes results of Brake Safety Week 2022 – Commercial Vehicle Safety Alliance | CarTailz

Commercial vehicle inspectors in Canada, Mexico and the United States conducted 38,117 commercial vehicle inspections from August 21-27 during Brake Safety Week. Of the total number of commercial vehicles inspected, 13.3% were disabled for violations of braking-related critical vehicle inspection points. It also means that nearly 87% of commercial vehicles inspected throughout North America during Brake Safety Week had no violations of brake-related critical vehicle inspection items.

The inspections carried out during Brake Safety Week are no different from the inspections carried out on other days of the year. During the week, inspectors collected brake-related data and then submitted it to Allianz for compilation, analysis and release.

Fifty-three Canadian and US jurisdictions, as well as Mexico’s Department of Communications and Transportation, participated in this year’s Brake Safety Week, a voluntary brake safety inspection and enforcement initiative.

By country, inspectors in Canada inspected 1,975 commercial vehicles and disabled 351 (17.8%) for brake-related violations. 1,740 commercial vehicles were checked in Mexico. Forty-four (2.5%) were decommissioned. In the US, of the 34,402 commercial vehicles inspected, 4,664 (13.6%) were taken out of service (OOS).

country number of inspections Number of inspections with OOS braking violations Percentage of vehicles that are OOS for braking violations
Canada 1,975 351 17.8%
Mexico 1,740 44 2.5%
US 34,402 4,664 13.6%
North America 38.117 5,059 13.3%

Inspectors also identified and documented 6,305 brake hose/tube chafing injuries, which is a common brake-related offense and was the focus of this year’s Brake Safety Week. Inspectors reported violations of brake hose chafing in four different categories of varying severity of chafing, including two that were non-operational violations.

1 Wear and tear extends to the outer protective material, if any. no 31% 34% 32%
2 The wear extends through the outer protective material and into the outer rubber cover. no 40% 22% 36%
3 Wear makes reinforcement layer visible,

but ply is intact.

4 Any part of the fabric/steel braid reinforcement layer is frayed, severed or cut through. Yes 12% fifteen% 19%

Additionally, 11 jurisdictions using performance-based brake testers evaluated the braking performance of 392 commercial vehicles during Brake Safety Week. 29 commercial vehicles failed their PBBT test – a failure rate of 7%. PBBTs, based on mechanical or electronic deceleration meters, evaluate the vehicle’s overall braking capability through a braking performance test that measures deceleration and/or stopping distance independent of brake type or actuation method.

During Brake Safety Week, the inspectors mainly performed the North American Standard Level I or Level V inspection. Both test levels include a thorough check of the braking systems and components. Inspectors look for missing, non-functioning, loose, cracked, or broken parts, such as: B. Spider castings, return springs, brake drums or rotors, brake shoes, linings or brake pads and slack adjusters. They also check for contaminated pads or pads, unmade holes in spring brake housings, S-Cam flip-overs, and audible air leaks. They check for mismatched brake cylinders on an axle, air reservoir security, hose and line condition, system air pressure, breakaway coupling, tractor protection system, pushrod travel and brake system warning devices.

Vehicles that did not encounter any vehicle and driver immobilisation violations during a Level I or Level V inspection may have received a CVSA sticker that provides inspectors with a visual indicator (valid for three months) is that the vehicle was recently inspected and had no critical violations of vehicle inspection items.

In June, the Commercial Vehicle Safety Alliance (CVSA) announced this year’s dates for Brake Safety Week, August 21-27. Allianz announces these dates in advance to remind drivers and transport companies of the importance of proper brake maintenance and to encourage proactive vehicle maintenance ahead of the week. Next year’s Brake Safety Week is scheduled for August 20-26, 2023.

Brake Safety Week is part of CVSA’s Operation Airbrake program in partnership with the US Federal Motor Carrier Safety Administration, the Canadian Council of Motor Transport Administrators and the Mexican Ministry of Communications and Transportation. Operation Airbrake is a comprehensive program to improve commercial vehicle braking safety throughout North America. The aim is to reduce the number of accidents caused by faulty commercial vehicle braking systems by conducting roadside checks and educating drivers, mechanics, owners and others on the importance of proper brake inspection, maintenance and service.
