Bendix Spicer offers lighter air disc brake

Bendix Spicer Foundation Brake – a joint venture of Bendix Commercial Vehicle Systems LLC and Dana Corp. – unveiled at the Mid-America Trucking Show Wednesday, March 21, a lightweight package of its Bendix ADB22X air disc brake that it says could help weight-sensitive operations justify the selection of disc brakes over drum brakes. Peterbilt has added the ADB22X as an option on new on-highway truck builds, effective April 2.

The brake package features an aluminum hub and splined disc assembly that weighs up to 240 pounds less than drum brake configurations on a typical 6×4 tractor and up to 209 pounds less than other air disc brakes. The aluminum assembly reduces rotor dynamic stresses, improves thermal balance and offers longer brake life, Bendix Spicer says.
