HANOVER, GERMANY. Wabco has introduced what it calls the lightest air disc brake for the heavy-duty truck and bus market here at the IAA Commercial Vehicle show. The next generation brake requires no rim-side brake carrier, which cuts weight to 82 lb.

This design also improves pressure distribution in the rim-side pad, Wabco said, increasing the heat crack resistance of the rotor to better-utilize the pad material.

In addition, an exchangeable wear sensor is offered to continuously monitor pad wear.

“The high-performance Air Dosc Brake NG22 plus for heavy trucks and buses builds on our established PAN-range brake,” said Nikhil Varty, Wabco vp of Compression and Braking. “It also follows our most recent innovation in braking—the new generation Air Disc Brake for trailers, as well as trucks and buses up to 18 tons, which we premiered at IAA 2004. The enhanced version launched to the public today is applicable to an even wider range of vehicles than the 2004 model.”
