Brake Safety Week: September 6-12, 2015

Properly functioning brake systems are crucial to safe commercial motor vehicle (CMV) operation. CMV brakes are designed to hold up under tough conditions, but they must be inspected and maintained carefully and consistently so they operate and perform properly throughout the vehicle’s life. Brake Safety Week is an annual outreach and enforcement campaign designed to improve commercial vehicle brake safety throughout North America.

Brake Safety Week – September 6-12, 2015 – is part of the Operation Airbrake program sponsored by CVSA in partnership with the U.S. Department of Transportation’s Federal Motor Carrier Safety Administration (FMCSA). During the week-long brake safety campaign, CMV inspectors will conduct brake system inspections (primarily Level IV Inspections) on trucks and buses throughout North America to identify out-of-adjustment brakes and brake-system violations.

Brake-related violations comprise the largest percentage (representing 46.2 percent during Roadcheck 2014) of all out-of-service violations cited during roadside inspections. Improperly installed or poorly maintained brake systems can reduce the braking capacity and stopping distance of trucks and buses, which poses a serious risk to driver and public safety.

Brake inspections conducted during Brake Safety Week include inspection of brake-system components to identify loose or missing parts, air or hydraulic fluid leaks, worn linings, pads, drums or rotors, and other faulty brake-system components. Antilock braking systems (ABS) malfunction indicator lamps also are checked. Inspectors will inspect brake components and measure pushrod stroke when appropriate. Defective or out-of-adjustment brakes will result in the vehicle being placed out of service. Read more about the inspection procedure.

Additional inspections may include some Level I Inspections and, in ten participating jurisdictions, overall vehicle braking efficiency will be tested using performance-based brake testing (PBBT) equipment. These systems include a slow speed roller dynamometer that measure total vehicle weight and total brake force, from which braking efficiency is calculated. The minimum braking efficiency for trucks is 43.5 percent, required by U.S. federal regulation and the CVSA Out-of-Service Criteria.

Outreach and educational efforts by CMV inspectors, participating motor carriers and others in the industry also take place during Brake Safety Week and are integral to the success of the campaign.

In 2014, 13,305 vehicles were inspected during Brake Safety Week. View the 2014 results. More than 3.4 million brakes have been inspected since the program’s inception in 1998.

Operation Airbrake Inspection Procedure

 Inspection Items

  • Driver License
  • Registration
  • Low Air Warning Device
  • Pushrod Travel (Adjustment)
  • Brake Linings/Drums
  • Air Loss Rate (If leak detected)
  • Tractor Protection System

Operation Air Brake Inspection Procedure

STEP 1: Choose the Inspection Site

STEP 2: Safety Considerations

STEP 3: Check Air Brake Mechanical Components

STEP 4: Check Steering Axle Air Brake Mechanical Components

STEP 5: Check Brake Adjustment

STEP 6: Build the Air Pressure to 90 – 100 PSI

STEP 7: Check the Air Brake ABS System (If Applicable)

STEP 8: Test Air Loss Rate

STEP 9: Test Low Air Pressure Warning Device

STEP 10: Check the Tractor Protection System

STEP 11: Finalize paperwork, and provide the results to the driver (i.e. out-of-service, etc.)

NOTE: All inspections are to be identified as a Level IV inspection.

NOTE: The statistics will require a count of automatic slack adjuster vs. manual slack adjuster brakes and their respective adjustment (or out of adjustment). Jurisdictions will need to capture this information on their CVSA inspection sheets or on some other form in order to compile the statistics. If the jurisdiction doesn’t normally capture this information on their inspection sheet, officers will need to know ahead of time that they are required to record this somewhere on the sheet.
