NHTSA Campaign 20V132000

SERVICE BRAKES, AIR

Issued by PACCAR Incorporated · Reported Mar 4, 2020 · 233 vehicles affected

What's 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."

Consequence

A delayed brake release may increase the risk of crash.

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.
