The Bendix ADB22X air disc brakes have a two-pin floating caliper design that provides a more stringent overall dimension accuracy and consistent force distribution. According to Bendix, the ADB22X design also significantly reduces brake fade with no degradation of stopping power.
The air disc brakes are available for a single rear axle with a GAWR of 19,000 to 23,000 lbs. with Hendrickson HAS air suspension or dual rear axles with a GAWR up to 40,000 lbs. with Kenworth AG400L suspension. Front axle coverage includes 10,000 lb. and 12,000 lb. capacities.
In December, Kenworth announced that it was making Bendix ADB22X front air disc brakes standard on its Class 8 tractors and trucks. The front air disc brakes were previously available as an option on Kenworth Class 8 models.
