More Reasons to Choose an Air Disc Brake for Tractor Applications
The new HDNABI™ Air Disc Brakes specially designed for Tractors
The HDNABI™ Air Disc Brakes have a brake rating of up to 23,000-lbs. per axle making them the perfect choice for the commercial Truck and Tractor market today. Based on the success of HDNABI™ XS5 22XLT™ and XS7 22XLT™ models, our design priority for high-performance, durability and light weight offers Fleets and operators a better alternative to drum brakes and competitive air disc brake systems. You can count on the same performance and durability you have come to expect from HDNABI™ Air Disc Brakes. The ADB system sets a new “standard of excellence” with solid long-life performance features that include a robust dual-piston caliper with synchronized 5-gear mechanism, precision auto-adjust sensing, proprietary matched eco-friendly copper-free pad and disc rotor. Another outstanding feature is the HDNABI™ brake actuator, a superior direct mount piston-type chamber, sealed and contamination free with internal zero back pressure breather, with low hold-off pressure design that reduces the risk of dragging brakes. When normal maintenance is required, pads changes are complete in 15 minutes per wheel position (With wheels off). Quick service and extended wear intervals equal lower cost-of-ownership for your commercial vehicles.
Built on a successful platform, the XS5 22XLT™ and the XS7 22XLT™ Air Disc Brakes share common replacement wear parts to simplify fleet maintenance, training, and service parts inventory requirements. That means you can reduce the cost-of-ownership even more by choosing HDNABI™ XS5 22XLT™ or XS7 22XLT™ for your Trucks. Upgrade now to HDNABI™ Air Disc Brake Systems for a safer and more reliable solution alternative to drum brakes.
