Service bulletin CSR 3074

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Altec Industries, Inc. has received notification from Peterbilt Motors Company that a condition exists relating to motor vehicle safety, compliance, or emissions in a vehicle you possess that is equipped with Altec equipment. Peterbilt has decided that a defect which relates to motor vehicle safety exists in certain 2020 through 2023 Model Year 536, 537, and 548 chassis built from 6/16/2020 through 1/25/2023 and equipped with Bendix 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. The risk of the brake plunger dislodging may be reduced by slowly releasing the service brakes and not allowing the pedal to release rapidly.
