What's wrong?
The foot brake valve assembly in affected 2021-2024 Peterbilt trucks is part of the air-brake system. When the driver presses the brake pedal, the pedal plunger links that pedal movement to the brake valve. The valve then sends air pressure through the service brake system so the truck slows or stops.
The problem is in the gap between the travel limit stop and the brake pedal. If that gap is too large, the pedal can rebound too far after a full brake application and quick release. That extra travel can let the plunger disconnect from the brake valve or become jammed, which can cause the service brakes to fail.
There is no warning sign before failure. The driver is not expected to hear, feel, or see an early symptom before the plunger disconnects or jams.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Service brake failure can increase the risk of a crash. There is no warning sign before failure, so treat an included VIN as a repair priority and avoid delaying the dealer visit. Repair is free at any franchised Peterbilt dealer.
What should I do?

- Contact a franchised Peterbilt dealer to schedule the free pedal restraint bracket repair that keeps the brake pedal plunger connected to the brake valve.
- Bring the recall notice if you have it. If not, reference recall number 23V087 and PACCAR recall 23PBB when you call.
