Meritor WABCO Vehicle Control Systems announced the availability of its proprietary single-piston PAN 22 Series air disc brake on three Meritor trailer suspensions – the new Meritor Trailing Arm air suspension 23,000-lb. unit and RideSentry air-ride trailer suspension MPA 20 and 38/40,000-lb. models. The brake can be specified immediately.

The lightweight disc brakes package includes the new Meritor integrated weld on the axle’s torque plate, an aluminum hub, flat-style rotor and axle ratings up to 23,000 lbs. An optimized pad size increases lining life to maximize vehicle uptime, while an integral molded friction pad impedes rust jacking.

“We continue to expand the availability of PAN 22,” says Mark Melletat, director of Trailer Systems and field operations for Meritor WABCO. ”Our reliable internal-sealed automatic adjuster lessens brake out-of-adjustments, along with minimal fade. This provides uniform stopping performance, which is especially important with the demands of today’s highly congested roadways. It’s a cost-effective and lightweight solution that is optimized for on-highway line haul axle ratings up to and including 23,000 pounds and ideal with 22.5-inch wheels.”

The PAN 22 also features a design that results in fewer parts to service while maximizing braking torque performance. Melletat says the brake is suited for customers who want the outstanding stopping performance, directional stability and superior fade resistance of an air disc brake, but “at a lifecycle cost that adds value to trailers.”
