- Summary
- Parts and repair procedures are now available. Kenworth has determined that a safety defect exists in certain Model Year 2021-2024 T280, T380, and T480 chassis with air brakes. The brake pedal plunger which connects the brake pedal to the brake valve may dislodge after the pedal is fully depressed, and rapidly released (side slip foot brake release). If the plunger in the brake pedal assembly dislodges, the driver may be unable to apply the service brakes, which may increase the risk of a crash.
