The Commercial Vehicle Safety Alliance (CVSA) held its annual national Brake Safety Week this fall. Of the 34,320 trucks CVSA inspected, 13.5% received out of service violations. While brakes are just one element of typical inspections, they are one of the leading causes of accidents. Failing to inspect brakes properly before driving long distances is a significant safety concern that CVSA highlights during its annual brake inspections. Inspectors noted the following as the most frequent tubing and brake hose violations:
- Thermoplastic hose chaffing: 1347 violations
- Thermoplastic hose kinking: 1683 violations
- Rubber hose chaffing: 2567 violations
- General misapplications of rule §393.45 of the FMCSA Regulations: 2704 violations
In promising news, highway fatalities are on the decline for the second year in a row. However, fatalities related to large trucks increased slightly. With the goal of zero highway fatalities, there is plenty of room for improvement when it comes to trucking safety.
How to Inspect Truck Brakes
Seasoned drivers may think their experience means they don’t make pre-trip inspection mistakes, but time has a way of eroding skills. Reviewing what officers look for during inspections can help prevent an unexpected out of service order. To get started on inspecting their brakes, drivers will need to do the following:
- Check brake adjustments when the truck is cold; heat expands the brake drum and can yield inaccurate results
- Inspect the brake chamber to ensure the size is correct
- Determine if the truck has standard or long-stroke chambers as this affects adjustment limits
- Measure the brake’s applied pushrod stroke
Depending on the final test results, drivers can learn if their brakes are out of alignment, by how much, and calculate if they’re within adjustment limits. If not, they can take the next steps necessary to realign the brakes during routine maintenance.
