Description

PACCAR Incorporated (PACCAR) is recalling certain 2016-2020 Peterbilt 320 and 520 vehicles with dual foot valves and a liftable tag or tri-drive rear axles. The rear brake signal hose may be missing a quick release valve, possibly causing a delay in their brake release timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Disc Brakes." A delayed brake release may increase the risk of crash.
