Possible brake issue leads to Kenworth T680 recall

Updated Oct 13, 2020

Paccar is recalling more than 1,400 Kenworth T680 tractors for a potential issue with a certain brake system, according to National Highway Traffic Safety Administration documents.

The recall affects about  1,416 model year 2016-2021 T680 trucks equipped with a 2.1m cab and Wabco 6S/6M ABS brake system with drum brakes.

Paccar says 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, increasing stopping distance of the trucks.

Paccar will notify owners, and dealers will replace the standard valve with a quick release valve for free. Owners can contact Paccar customer service at 1-425-828-5888 with recall number 20KWD. NHTSA’s recall number is 20V-593.
