Recall 20V593000
NHTSA safety recall campaign 20V593000. Component: SERVICE BRAKES, AIR:ANTILOCK. 1,416 units potentially affected.
Risk Summary (Consequence)
Longer than expected service-brake release timing may lengthen vehicle stopping distance, increasing the risk of a crash.
Defect Summary
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."
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.
