AIR DISC BRAKES
New Generation
Proven safety performance and significant weight reduction
Within the scope of WABCO’s continuous improvement and development processes and the mission to provide worldwide customers with state-of-the-art technology, WABCO now presents a new generation of air disc brakes, building on the successful PAN range. Research into the shapes and designs found in nature has revealed superior technical concepts and constructions to those developed by man. By applying the concepts and principles of this research, known as Bionics, a new generation of air disc brakes combining lightweight structures with high performance has been created. As a result, WABCO's new generation of air disc brakes combines safety with a considerable reduction in weight.
The differentiating feature of WABCO’s latest generation of air disc brakes is the new brake caliper with pad off-set. The moment acting on the caliper by braking is compensated such that the rim-sided pad can be retained and supported in the caliper. Eliminating the rim-sided brake carrier results in a distinct weight reduction as well as improving the pressure distribution of the rim-sided pad. Furthermore, the new generation of air disc brakes can also be easily adapted to the axle and installation requirements of different customers worlwide.
Benefits The reduced weight of WABCO’s new generation of air disc brakes makes them the lightest brakes in the 22.5” rim size. Improved pressure distribution of the rim-sided pad improves disc cracking resistance and minimizes radial and tangential taper wear. This facilitates optimal pad utilization. The WABCO’s new generation of air disc brakes retains the proven, patented single-piston technology of the earlier PAN range, whose compact and reliable design has given customer satisfaction for many years. The service friendliness of the PAN range, including the
radial pad change and lifetime lubrication, has also been transferred to this new generation.

WABCO WORLDWIDE
WABCO, the vehicle control systems busi-
ness of American Standard Companies, is the world’s leading producer of elec tronic braking, stability, suspension and transmission control systems for heavy duty com-
mercial vehicles. WABCO products are also increasingly used in luxury cars and sport utility vehicles (SUVs). Customers include the world’s leading commercial truck, trailer, bus and passenger car manufacturers. Founded in the US 135 years
ago as Westinghouse Air Brake Company, WABCO was acquired by American Standard in 1968. Headquartered in
Brussels, Belgium, the business today employs nearly 6500 people in 29 office and production facilities worldwide. In 2003, WABCO contributed US$ 1.358 billion to American Standard’s total sales of US$ 8.568 billion. Website: www.wabco-auto.com
