NHTSA Campaign 20V593000
SERVICE BRAKES, AIR:ANTILOCK
Issued by PACCAR Incorporated · Reported Sep 28, 2020 · 1,416 vehicles affected
What's wrong
PACCAR Incorporated (PACCAR) is recalling certain 2016-2021 Kenworth T680 trucks equipped with a 2.1m Cab and WABCO 6S/6M ABS brake system with drum brakes. The brake systems were manufactured with a standard rear-brake ABS modulator valve instead of a quick release valve, which may exceed the intended service-brake release timing. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
Consequence
Longer than expected service-brake release timing may lengthen vehicle stopping distance, increasing the risk of a crash.
Remedy
PACCAR will notify owners, and dealers will replace the standard rear-brake, ABS modulator valve with a quick release valve, free of charge. The recall began November 30, 2020. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR's number for this recall is 20KWD.
