With the introduction of pneumatic disc brake PAN 17 in 1996, WABCO pioneered to control tangential taper wear. Since then, WABCO patented taper wear compensation in combination with advanced WABCO patented single-piston technology has generated strong customer satisfaction.

Our success in 17,5" wheel applications demonstrates the effectiveness of this technology.
