The Hendrickson MAXX22T air disc brake system is optimized for trailer applications and aligns with the braking requirements of North American tractor-trailer combinations. The braking system combines WABCO’s bi-directional single piston design with Hendrickson's wheel end and brake components for higher reliability, reduced weight and installation efficiency. The MAXX22T system features a bolt-on splash guard for easier installation and maintenance. It is corrosion resistant, and the design allows for simplified rotor inspection. The MAXX22T air disc brakes are rated up to a 20,000 lbs gross-axle weight with tires as large as 20.8" tire static loaded radius (SLR).
