## 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.
