The Bendix ADB22X-LT is the first Bendix air disc brake engineered specifically for trailers and is now available in North America.
The ADB22X-LT has a 23,000-pound brake rating and is 40 pounds per tandem axle lighter than its companion ADB22X air disc brake making it the lightest air disc brake in Bendix’s lineup. Lighter wheel-ends deliver increased payload capacity and can be a value for trailers that are particularly sensitive to brake weight. Lighter weight can also improve overall fuel efficiency.
Utility Trailer Manufacturing Company will be the first trailer builder to offer the new air disc brake.
“Though the ADB22X-LT has been specifically designed for trailer use, it’s built on the same proven, successful platform as the ADB22X brake,” McComsey said. “The two brakes share replacement wear items, which helps to streamline maintenance and training plus reduce inventory requirements. In addition, the same skill sets fleet technicians use for installing and maintaining the ADB22X are equally applicable to the ADB22X-LT, making it a great candidate for installation by trailer builders.”
The ADB22X-LT brake features a new pad with 8% more wearable volume and up to a 40% improvement in wear rate, according to Bendix. The new pad also meets the EPA’s 2021 copper-free brake initiative requirements.
A new adjustment mechanism also supports longer service life by improving pad life and further reducing the risk of brake drag. Air disc brakes like the ADB22X-LT offer quicker pad replacement than foundation drum brakes, combined with longer brake lining life and straight, stable stops. Since air disc brake pad friction is not riveted like drum brake friction, rust jacking is not an issue. A reduction of brake fade or degradation of stopping power increases reliability, and the brake’s internal self-adjustment mechanism can help lower the risk of brakes being found out of adjustment during inspection
The Bendix ADB22X-LT offers the same 5-year warranty as the ADB22X air disc brake.
