Mack Adds Air Disc Brakes to Vocational Truck Lineup

01-21-2014 
LAS VEGAS (January 21, 2014) – Work truck customers looking for superior stopping performance in harsh conditions and duty cycles can now order Meritor EX+ Air Disc Brakes for their MACK® Granite®, TerraPro® and Titan by Mack models. Mack introduced the air disc brakes offering across its vocational lineup today at the 2014 World of Concrete exhibition. 

“Mack’s air disc brakes are built to our standards and tuned specifically for the needs of vocational customers to help boost uptime and lower overall lifecycle costs,” said Stu Russoli, Mack vocational marketing product manager. “Vehicle operators and workers on the job site can also enjoy the added safety benefits of the air disc brakes’ exceptional stopping performance.”

More than 2.2 million miles of real-world service in North America has shown that the air disc brakes deliver superior stopping performance and require less maintenance than conventional S-cam designs. Mack’s air disc brakes utilize a flat rotor concept to prevent heat distortion in heavy-duty service, rather than “hat-shaped” rotors, which are prone to distortion and shorter life. The brake pads are engineered by Mack to deliver top performance in all situations and minimize brake fade during extreme braking cycles and frequent use.

“In line with our philosophy of application excellence, our air disc brakes are optimized to give customers a durable option for excellent performance in any type of work environment,” said John Walsh, Mack vice president of marketing. 

Mack began offering air disc brakes in 2008 on its MACK® Pinnacle™ Axle Forward and Axle Back models.
