Starting this Sunday, September 6th to Saturday, September 12th, CMV inspectors will be out conducting brake system inspections as part of the CVSA’s Operation Air Brake Safety Week. It is a partnership with the FMCSA and sees Level IV inspections happening on trucks and buses throughout North America to identify out of adjustment brakes, safety issues, and brake-system violations. Brake-related violations account for nearly half of all out-of-service violations during roadside inspections.

What are inspectors looking for?

Brake inspections will include assessments of brake-system components to identify loose or missing parts, air or hydraulic fluid leaks, worn linings, pads, drums or rotors. Antilock braking systems (ABS) malfunction indicator lamps will also be checked. Inspectors will also measure pushrod stroke when appropriate. Here’s the full process that will happen with each inspection:

Items to be inspected:
• Driver License
• Registration
• Low Air Warning Device
• Pushrod Travel (adjustment)
• Brake Linings/Drums
• Air Loss Rate (if a leak detected)
• Tractor Protection System

Operation Air Brake Inspection Steps:
Step 1: Choose the inspection site
Step 2: Review 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.)

In 2014, more than 13,000 vehicles were inspected during Brake Safety Week (View the 2014 results). This year, more than 13,000 brake inspections are also expected to be conducted.

The CVSA has created various resources and educational materials for drivers, mechanics, and industry stakeholders. A great one is the video below produced by the DOT on Antilock Braking Systems:

Keep those brake systems in check; Make sure you and your truck are prepared for next week!
