Hendrickson Launches Air Disc Brake for Trailers

LOUISVILLE, Ky. — Truck-and-trailer suspension and axle supplier Hendrickson Trailer Commercial Vehicle Systems launched an air disc brake system for trailers March 26 at the Mid-America Trucking Show here.

Aimed at the growing market for air disc brakes on trailers, Maxx22T combines Hendrickson technology with an air brake system supplied by Wabco, the company said. Perry Bahr, vice president and general manager for Hendrickson’s trailer business, said the Wabco brakes are optimized for North American trailer applications. 

“Disc brake technology is continuing to gain popularity” because disc brakes do not fade, or lose braking power, as drum brakes do, Bahr said.

“One size does not fit all when it comes to air disc brakes,” he said in the announcement. “The forces that dictate a brake system’s design differ between the tractor and trailer.” Bahr said Hendrickson’s experience with trailer suspensions and brakes helps the company produce a system “that aligns with the braking requirements of North American tractor-trailer combinations.”

The company said the Maxx22T is available on most of Hendrickson’s INTRAAX and VANTRAAX suspension systems.

The air disc brake system features a bolt-on splash guard that is coated for corrosion protection and designed to allow simplified rotor inspection.

Hendrickson is offering the disc brake system to all major trailer manufacturers and that the package adds about $1,000 per axle, compared with drum brakes. That price “will come down over time,” Bahr said.
