Description
Safety Recall 23KWB: T280/T380/T480 Bendix Brake Pedal Plunger
Safety Recall
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.
Introduction
It was observed on certain T280, T380, and T480 chassis with air brakes that the pedal plunger which connects the brake pedal to the brake valve, may become dislodged, when the pedal is fully depressed and released extremely rapidly (side slip foot brake release).
The plunger dislodging in the brake pedal assembly may occur without warning and result in the driver being unable to apply the service brakes, which may increase the risk of a crash.
Situation
4,209 (3,993 U.S. and 216 CAN) Model Year 2021-2024 T280, T380, and T480 chassis built between 06/17/2020 and 01/17/2023 with air brakes.

01-25-23: Warranty search completed, and no relevant claims identified. Additional evaluations at other Paccar facilities were able to replicate the issue on 2.1m medium duty vehicles.
01-26-23: Rework procedure approved by Paccar and Bendix. Rework begins at plants.
02-08-23: Investigation details summarized and warranty search updated. No relevant claims identified.

Description of Remedy :
Description of Remedy Program : The defect is remedied by adding a pedal restraint bracket. The bracket
limits the pedal travel in the rebound direction and the plunger cannot become dislocated or jammed. Owners who incurred costs to obtain a remedy for the problem addressed by the recall in advance of receiving notification may seek reimbursement through the process outlined in the general reimbursement plan on file. How Remedy Component Differs from Recalled Component : Identify How/When Recall Condition was Corrected in Production : The remedy agreed to by both Bendix and PACCAR includes the addition of a restraint bracket that limits the rebound travel of the pedal such that the pedal plunger cannot become dislocated or jammed.
The excessive gap between the pedal travel limit and the pedal was eliminated to prevent the pedal plunger from becoming disconnected or jammed. The condition was corrected in production for all vehicles built on or after January 18, 2023.
