The Meritor EX+ LS Air Disc Brake is designed to meet growing fleet expectations for efficiency, safety, and weight reduction. Built with taper wear control, the air disc brake is 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, says the company. The EX+ LS Air Disc Brake comes standard with MA9300 N-level proprietary friction.
