Bendix has announced the release of the ADB22X-LT air disc brake designed specifically for trailers. Bendix unveiled the ADB22X-LT in conjunction with Utility Trailer Manufacturing Co., the first builder to offer the new brake.
“In the decade since Bendix introduced the first air disc brake to the North American commercial vehicle market, we’ve had many customers equip their trailers with ADBs; their positive feedback and effective on-road experience played a big part in developing the ADB22X-LT,” said Keith McComsey, director of marketing and customer solutions for Bendix Spicer Foundation Brake. “We put Bendix’s wide-ranging braking expertise to work to help meet the challenges presented in trailer applications, and the end result is an air disc brake that offers the advantages of lighter weight and more convenient servicing – while still performing at the high levels demanded in today’s trucking environment.”
The Bendix ADB22X-LT, with a 23,000-lb. brake rating, weighs in at 40 lbs. per tandem axle lighter than its companion Bendix ADB22X air disc brake, making it the lightest air disc brake available in North America. Lighter wheel ends deliver increased payload capacity and value for trailers, such as refrigerated unit, particularly sensitive to brake weight. Bendix said, adding that lighter-weight wheel ends can also help a fleet significantly improve its overall fuel efficiency.
The ADB22X-LT brake features a new pad with 8% more wearable volume and up to a 40% improvement in wear rate. The new pad meets the Environmental Protection Agency’s 2021 Copper-Free Brake Initiative requirements. In addition to the new pad, the 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, car-like feel and straight, stable stops. Since air disc brake pad friction is not riveted like drum brake friction, rust jacking is not an issue, according to the company. A virtual absence 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, which can affect Compliance, Safety, Accountability (CSA) scoring, the company said. The Bendix ADB22X-LT offers the same 5-year warranty as the ADB22X air disc brake.
