Throughout Brake Safety Week, inspectors will conduct their usual inspections; however, in addition, they will be reporting brake-related inspection and violation data to CVSA and could affect a motor carrier’s safety rating.
When inspectors conduct the brake portion of a Level I or Level V Inspection, they will:
Check for missing, non-functioning, loose or cracked parts.
Check for contaminated, worn, cracked and missing linings or pads.
Check for S-cam flipover.
Listen for audible air leaks around brake components and lines.
Check that slack adjusters are the same length (from center of S-cam to center of clevis pin) and the air chambers on each axle are the same size.
Ensure the brake system maintains air pressure between 90-100 psi (620-690 kPa) and measure pushrod travel.
Inspect for non-manufactured holes (e.g., rust holes, holes created by rubbing or friction, etc.) and broken springs in the spring brake housing section of the parking brake.
Inspect required brake system warning devices, such as anti-lock braking system (ABS) malfunction lamp(s) and low air-pressure warning devices.
Inspect the tractor protection system, including the bleedback system on the trailer.
Ensure the breakaway system is operable on the trailer.
