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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10236331-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10236331-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10236331","components":[{"id":"brakes","name":"Brakes","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ALTEC","model":"AERIAL DEVICE","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
