Meritor WABCO Vehicle Control Systems announced the availability of its patented 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.
According to the announcement, with 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., the air disc brake model has become one of the lightest disc brakes packages available today. The lightweight and long pad life single piston air disc brake utilizes WABCO’s tested and field proven technology.
An optimized pad size increases lining life to maximize vehicle up time. An integral molded friction pad virtually eliminates rust jacking.
“We continue to expand the availability of PAN 22 – which is now available on the most popular trailer suspensions in the industry,” said 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 lbs., and ideal with 22.5 inch wheels.”
The company said that at 79 pounds including pads, the PAN 22 weighs less than any other air disc brake in its class. It also features a design that results in fewer parts to service. It also delivers powerful braking torque performance – up to 24,000 Nm. It has larger, thicker pads than competitive designs, which results in longer pad replacement intervals, the company said.
Melletat added that the brake is perfect for customers who want the outstanding stopping performance, directional stability, and superior fade resistance of an air disc brake but “at a life-cycle cost that adds value to trailers.”
