Mack Trucks now offers Bendix ADB22X heavy-duty air disc brakes on the Mack Pinnacle axle-forward and axle-back models. And Volvo has made a similar announcement, saying they’ll offer the disc brakes on its VN and VT model trucks.
Disc brakes are noted for their superior braking performance, resistance to fade on long downhill descents, ease of maintenance, and longer component life. They fit well in applications demanding optimum on-highway braking performance. Mack is initially offering the disc brakes on 12,000-lb front and 40,000-lb rear supplier axles.
