Meritor WABCO, a joint venture between ArvinMeritor and WABCO Vehicle Control Systems, has extended its PAN air disc brake family in North America with the introduction of the PAN 22. This advanced single-piston air disc brake is designed for North American commercial trailers with 22.5-inch wheels and axles rated to 22,000 pounds.

Available as a trailer OEM option, the single piston air disc brake family will also be provided for tractors, trucks, and buses, since its compact design and low weight offer operational advantages.

At 79 pounds including pads, the PAN 22 weighs less than other air disc brakes in its class. It also delivers powerful braking torque performance — up to 24,000 Nm. It has larger, thicker pads, resulting in longer pad replacement intervals.

The PAN 22 incorporates the same single-piston clamping unit design used in PAN 17 and PAN 19 air disc brakes. Compact and efficient — with just 18 parts — the single-piston clamping unit helps reduce weight and complexity and allows for a compact design that easily adapts to axles, wheels, and suspensions. It compensates for taper wear and enables optimal pad wear use. The encapsulated guiding system with metal protective covers enhances reliability and durability.
