TROY, Mich. –Three more Meritor trailer suspensions can now be spec’d with the Meritor Wabco single piston PAN22 Series air disc brake. Covered are the new Meritor Trailing Arm air suspension 23,000-lb unit and the MPA 20 and 38/40,000-lb versions of the Ride-Sentry air-ride trailer suspension.

Disc brakes are available on the three models immediately, Meritor announced.

“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 PAN 22 weighs 79 lbs including pads, which Meritor says makes it the lightest air disc brake in its class. Melletat said the offering is ideal for customers looking for outstanding stopping performance, directional stability and excellent fade resistance at a life-cycle cost that adds value to the trailers.
