Bendix ADB22X Air Disc Brake Now Standard on all Axles of Kenworth T680

Testing has shown that from 60 mph, a tractor equipped with air disc brakes on all axles stops about 15 ft. shorter than one equipped with steer-axle air disc brakes alone.

The Bendix ADB22X air disc brake (ADB) will now come standard on all axles of the Kenworth T680, further enhancing the stopping power of Kenworth Truck Company’s flagship on-highway tractor. Since 2013, the top-performing ADB22X has been offered as standard equipment on T680 steer axles. 

“The Kenworth T680 has a well-earned reputation as a top performer – thanks, in part, to the diligence of the Kenworth team when it comes to safety technology adoption. In addition to air disc brakes on all axles, standard equipment includes the Bendix ESP full-stability system and Bendix Wingman Advanced – A Collision Mitigation Technology,” says Scott Burkhart, Bendix Vice President – Sales, Marketing, and Business Development. “We’re very proud of our long partnership with Kenworth, and we look forward to millions and millions of miles of safe performance.”

Bendix testing has shown that from 60 mph, a tractor equipped with air disc brakes on all axles stops about 15 ft. shorter than one equipped with steer-axle ADBs alone. Air disc brakes also offer additional safety benefits by virtually eliminating brake fade and brake steer, providing straighter, more consistent stops.

“Fleets and truck operators purchasing new Kenworth T680s can benefit from the superior performance, automotive-like feel, lightweight design, and ease of maintenance offered by Bendix ADB22X front and rear air disc brakes,” says Kurt Swihart, Kenworth Marketing Director. “These brakes also exceed the federal government’s RSD (reduced stopping distance) requirements for enhanced safety, offer extended brake change intervals, and provide weight reduction.”

The ADB22X is produced by Bendix Spicer Foundation Brake LLC (BSFB), a joint venture between Bendix Commercial Vehicle Systems LLC and Dana Commercial Vehicle Products, LLC. Since launching the ADB22X in 2005, BSFB has produced well over 2 million units, reflecting an ever-increasing demand for air disc brakes in the commercial vehicle industry. Worldwide, Bendix and its parent company, Knorr-Bremse, are the clear global leader in air disc brake production at nearly 40 million and counting.

Advantages Add Up

Equipping the Bendix ADB22X on all axles of a tractor helps reduce a fleet’s total cost of ownership (TCO), in addition to providing safety and performance benefits.

In the garage, uptime is enhanced thanks to extended friction service intervals and the potential to eliminate a friction change – depending on fleet operator trade cycles, mileage, and other factors. If a friction change is required, the ADB advantage means pad changes take just one-quarter the time of drum bakes once the wheel is removed.

The Bendix air disc brake design also eliminates the risk of cracked friction resulting from rust jacking, while its internal self-adjustment mechanism helps lower the risk of brakes being found out of adjustment during inspection – which can affect Compliance, Safety, Accountability (CSA) scoring.

Bendix Spicer Foundation Brake contributes to the full lineup of Bendix safety and trailer solutions, including the array of commercially available Bendix brand air disc brakes and foundation drum brakes produced at its state-of-the-art manufacturing facility in Bowling Green, KY. The broad range of Bendix wheel-end offerings includes air disc and drum brake systems, automatic slack adjusters, spring brakes, friction, and remanufactured brake shoes.

Through improved vehicle performance and efficiency, plus unparalleled post-sales support, BSFB helps strengthen return on investment in technologies that enhance vehicle and driver safety.
