Centric Fleet Performance brake pads are manufactured using the same positive molding process utilized by Original Equipment suppliers. Positive molding uses extreme pressure to compress the friction material and bond it to the backing plate. This process assures consistent friction material density throughout the pad, resulting in even wear and performance characteristics throughout the life of the brake pad. Para-aramid friction compounds are specially formulated to provide linear response at both cold and hot temperatures. Positive Mold Technology. Precision cut backing plates. Scorched for improved pad/rotor bed-in. 1989 - 1991 Iveco Euro Turbo Range 23-16, 1987 - 1990 Iveco EuroTurbo 335T, 1987 - 1990 Iveco EuroTurbo 340T, 1987 - 1990 Iveco EuroTurbo 435T, 1987 - 1990 Iveco EuroTurbo 450T, 2006 - 2008 Workhorse Custom Chassis W42, 2006 - 2009 Workhorse P500 - Fedex Delivery Truck, 2001 - 2009 Workhorse W16, 2001 - 2009 Workhorse W18, 2006 - 2011 Workhorse W42
