LOUISVILLE, Ky. — Bendix Spicer Foundation Brake, a wheel-end joint venture between Bendix Commercial Vehicle Systems and Dana Corporation, announced the launch of a lightweight package of its Bendix ADB22X air disc brake product.

Peterbilt has added the technology as an option on new on-highway truck builds effective April 2, Bendix also revealed during the Mid-America Trucking Show in Louisville, Ky. on March 21.

A commitment to testing, research and development, training, and product innovation will ensure Bendix Spicer Foundation Brake of continued growth for decades to come, according to company officials.

By expanding our product offering to include solutions that meet the needs of a variety of axles, vocations, and applications, weve been able to further grow beyond our more traditional commercial, over-the-highway vehicle markets into some niche markets, said Alf Siebke, director, air disc brakes, Bendix Spicer Foundation Brake. Additionally, our aggressive testing and R&D allow us to continue to validate performance, understand and improve the longevity of brakes, and prepare for NHTSAs proposed stopping-distance requirements.

The lightweight air disc brake package features an aluminum hub and splined disc assembly to reduce total wheel-end weight, reduce rotor dynamic stresses, provide improved thermal balance and offer longer brake life.

The aluminum splined disc can save as much as 240 pounds (total) compared with drum brake configurations on a typical 6×4 tractor and offers savings of 209 pounds (total) compared with other air disc brakes, which use an iron hub and conventional rotor on the same typical tractor configuration, noted the manufacturer.

In addition to weight savings, the Bendix ADB22X air disc brake package is manufactured using Bendix rotor metallurgy and friction formulations, in an effort to add longevity to the brake components while maintaining performance.

This product enhancement demonstrates a significant breakthrough in air disc brake technology, said Siebke. It also signifies our growth as a company and our continued efforts to be a leader in foundation brake innovation and technology.

The Bendix ADB22X model is built on proven, high-volume technology from the Knorr-Bremse Group, European affiliate for Bendix. Extensive air disc brake product testing has proven it to provide stopping distances comfortably within the range of NHTSAs proposed 20% to 30% percent reduction.

Bendix brand air disc brakes are compatible in a variety of combinations with North American tractor and trailer air drum foundation brakes.

The company also recently introduced new pad and rotor dust shield technology, which incorporates the technology used to protect brake pads and rotors in harsh environments and conditions, extending the life of air disc brakes. The pad and rotor dust shields can also be used in conjunction with wide-base single tires.
