“After years of development, more than 300 lab tests and over 1 million miles of validation on the road, our EX+ LS air disc brake is designed to offer the reliability and performance that customers expect from Meritor,” said T.J. Reed, vice president of Front Drivetrain and Electrification.

The new air disc brake is designed and validated to the same taper wear criteria as a twin-piston brake. Its large-diameter, integrated piston and pusher plate reduce taper wear by increasing stability to deliver evenly distributed braking forces across the brake surface. The adjuster mechanism is based on proven EX+ air disc brake architecture to offer reliable and consistent brake performance.

The EX+ LS air disc brake comes standard with MA9300 N-level proprietary friction. Optional positive pad retraction is designed with the goal of maintaining friction couple running clearance to extend pad life and reduce brake drag. An optional pad wear warning indicator aids in service predictability. 

Fleets with EX+ LS air disc brakes on their trucks and trailers benefit from commonality of parts within Meritor’s existing EX+ L air disc brake design, according to Meritor. They can stock fewer parts and replacement is simplified by ordering through Meritor Aftermarket. 

The EX+ LS air disc brake is available globally under the ELSA air disc brake product line outside North America. DriveForce, Meritor’s North American sales and service organization, and OnTrac, Meritor’s dealer technical support center, are available to assist customers with solutions before, during and after the sale.
