The defect
PACCAR Incorporated (PACCAR) is recalling certain 2012-2018 Kenworth T800 and T880 vehicles equipped with Neway ADZ tridem rear suspensions. The brake control airline may be the incorrect size, resulting in an imbalance in the service brake application timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air brake systems."
The risk
An incorrectly sized airline may lengthen the distance needed to stop the vehicle, increasing the risk of a crash.
