Mack Trucks Inc now offers Bendix ADB22X heavy-duty air disc brakes on the Mack Pinnacle axle forward and Mack Pinnacle axle back models. Mack showed a Pinnacle with air disc brakes on all axles during the 2008 Great American Trucking Show August 21-23 in Dallas, Texas.

Disc brakes are noted for their superior braking performance, resistance to fade on long downhill descents, ease of maintenance, and longer component life, according to Jerry Warmkessel, Mack highway products marketing manager. They are attractive to customers with especially demanding on-highway braking requirements, and complement the enhanced performance and safety of the Mack Roll Stability Advantage system that is standard on the company's highway vehicles.

Mack is initially offering the Bendix disc brakes on 12,000-lb steer and 40,000-lb rear tandem drive axles. Putting air disc brakes on all three tractor axles cuts vehicle weight by about 159 pounds compared to drum brakes.
