ATLANTA – Meritor announced its EX+ air disc brake for tractors and trailers has been optimized to reduce product weight and total cost of ownership. The optimized EX+ will be available to OEMs in 2018.

"We're focused on product development to make air disc brake sytems more lightweight and cost effective," explained T.J. Reed, vice president, front drivetrain, North America, at the North American Commercial Vehicle Show. He pointed out that Meritor has been designing and manufacturing brakes for more than 100 years. "You may think of Meritor as a drivetrain or axle company, but ... we had first axle brake integration program right before WWI."

Meritor engineers reduced the weight of the caliper by 10 pounds without offsetting any brake performance, Reed said. "We are so confident that we improved the warranty to 5 years/500,000 miles for linehaul applications."

The gear-synchronized, twin-piston design of the new EX+ delivers even force across the brake pads simultaneously, resulting in better performance and uniform pad wear. The EX+ optimized ADB offers shorter and smoother stopping distances and reduced brake fade. A patented double-sealing technology minimizes water exposure to seal the EX+ for life. It simplifies pad service steps – including 30-minute pad changes – and lowers maintenance costs with faster inspection and repair times.

"Fleets are beginning to see the benefits of air disc brakes, especially in safety and performance," said Chris Villavarayan, president, Americas for Meritor. "We have validated the EX+ in the most severe conditions to deliver superior performance and lower lifecycle costs."

Reed also noted that Meritor air disc brakes are compatible with most collision mitigation systems currently on the market. Fleets can also specify drum brakes on rear axles and ADBs on the front.

Meritor's improved standard warranty now offers coverage of five years and 500,000 miles for both parts and labor on linehaul applications when specified with Meritor's exclusive friction. Meritor brakes are backed by DriveForce^™ – Meritor's North America sales and service organization – to assist customers before, during and after the sale.
