Bendix has slashed the weight of its ADB22X air disc brake, making it what it claims to be the lightest disc brake assembly on the market.

The ADB22X-LT will be released in the second half of this year, for linehaul fleets and others that are weight-sensitive.

The company says redesigned geometry removed weight from the caliper and carrier, while maintaining comparable torque ratings.

“To meet their lighter-duty needs, fleets and owner-operators wanted a lower-weight air disc brake with all the performance, safety, and maintenance advantages of the original ADB22X,” said Mark Holley, director of marketing and customer solutions, wheel-end, at Bendix.

“Our new, optimized version delivers a premium braking solution capable of meeting a wide range of these needs, including linehaul. The lower weight – a reduction of 7.2 lb. – per wheel end, or 28.8 lb. for a 6×4 or 6×2 configuration, translates into increased payload capacity and improved fuel efficiency. When you add in the improvements we’ve made to the ADB22X in the past few years, the result is a brake that makes sense both on the road and from the perspective of total cost of ownership.”
