Chicago Ridge, Ill. — (Release Wire) — 09/09/2022 —

As usual during Brake Safety Week, inspectors will handle standard brake inspections according to North American Tier I and V standards, as well as collect and report brake data to CVSA. This year, the focus will be on the total number of inoperative brake inspections and violations, and inspectors will also collect and report data on brake hose/tube abrasion violations. The results of their work will not be published until the fall.

Historically, brake violations represent the highest percentage of all violations that result in unserviceable vehicles being detected during traffic inspections. During the three-day International Roadside Inspection last year, brake adjustment and braking system data accounted for 38.9% of all inoperable vehicle violations, the highest of any violation category. .

In preparation for the event, the CVSA reminds drivers and carriers of the importance of proper brake maintenance and pre- and post-trip vehicle inspections, and encourages motor carriers to perform preventative vehicle maintenance. HMD Trucking, along with other trucking companies, tries to pay maximum attention to brake system performance and recommends:

Check daily:

  • Check for damaged or loose inner tubes, lifters or slack adjusters.

  • Make sure the slack adjusters on each axle are extended at the same angle, as different angles can indicate an out of adjustment brake or a broken brake spring.

  • Inspect the general condition of the tubes and hoses, their location and their connections.

    Once a week:

  • Pressurize the brake system to 90-100 psi with the wheels removed and the parking brakes released and listen carefully for leaks.

  • Check air disc brake rotors for cracks.

  • Check drum brake pads for wear and cracks.

    Once a month:

  • Check the moisture in the air system to prevent contamination that will cause component wear and system leaks.

    The company has its own repair and maintenance workshop, which ensures optimal performance of truck brakes at all times. Learn more about hmdtrucking.com.

    ASVC is positioning the event as an opportunity for inspectors to conduct brake safety education and awareness activities.

    Inspectors will look for loose, missing, non-functioning, dirty, or cracked brake system parts, as well as holes due to rust or friction. They will also look for non-functioning springs in the parking brake housing.

    It is important to ensure that pneumatic systems maintain a pressure of 90 to 100 psi. To do this, inspectors will listen to systems for audible leaks. During the cabin inspection process, emphasis will be placed on devices that warn of low air pressure in the brake systems.

    Inspectors will check to see if the S-cam is upside down, use a ruler and chalk to measure the travel of the tappets, and check that the slack adjusters are the same distance between the center of the S-cam and the center of the Tightening. pin. Inspectors will also check that the tubes on each axle are the same size.

    They will also make sure the trailer disconnect system is working and check the tractor’s safety system, including the air bleeding system on the trailer, check the required braking system warning devices, such as ABS fault lights and low air pressure warning devices.

    In emergency situations on the road, fractions of a second count. Therefore, proper operation of heavy duty vehicle brake systems is of the utmost importance. Improper maintenance of the braking systems of large trucks and coaches can significantly reduce their braking ability and stopping distance, which can pose a significant risk to the safety of all road users.

    In 2021, inspectors in Canada checked approximately 2,000 commercial vehicles during Brake Safety Week. There were 15.4% failures, not at all significantly higher than the 13.5% reported in the United States. Across North America, 35,764 vehicles were inspected and 5,667 violations were found to be related to brake hose failures.
