What is wrong
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."
What can happen
A delayed brake release may increase the risk of crash.
The remedy
PACCAR will notify owners, and dealers will check the vehicles for a quick release valve, installing one as necessary, free of charge. The recall began March 24, 2020. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 20PBB.
