The DiscPlus product family has been introduced by Rockwell Automotive's Worldwide Truck & Trailer Systems as a "new generation " of heavy-duty air-actuated disc brakes. According to the manufacturer, DiscPlus produces shorter stops than tractor drum-brake setups, as well as greater braking efficiency than its own previous air-disc offerings.

"This new technology will benefit safety-conscious fleets by helping reduce the gap between heavy-truck and passenger-car stopping capabilities," said Ken Myers, general manager of brake systems. "DiscPlus can provide up to 16% shorter stopping-distance performance over conventional drum brakes."

The first model in the DiscPlus lineup is the DX195, a steer-axle brake designed to fit both 19.5- and 22.5-in. wheels. It will be available initially in a package with Rockwell Q Plus S-cam brakes on rear drive axles for Class 7 and 8 applications. Rockwell said this combination will provide performance -- "similar to that currently available on passenger cars" -- at a fraction of the cost of having air discs on all wheels.

The DX195 package will become available through OEMs beginning this month. It is aimed at "safety-conscious fleets" seeking "extreme-duty" performance from their brakes.

In other news, Rockwell Aftermarket Parts & Services announced a new "premium" cam-brake lining that it said can provide up to 30% longer lining life. In addition, the manufacturer said the lining can contribute to lower life cycle costs by extending time between relines.

Designated R208, the new lining will be initially available this month for heavy vehicles with axle ratings of 20,000 lb. The proprietary lining will be the first to feature Rockwell's new blue edge code for ease of identification. The edge code uses white block letters on a "distinctive" blue background to make it easy to read.
