Hybrid Disc Brake. A leader in hybrid friction material since the 1980’s, FDP manufactured the first hybrid production brake in 1984. Today, FDP’s Duostop® is the only hybrid disc brake with two different friction formulations on the same pad. Leading edge friction takes the heat and provides excellent fade resistance.Trailing edge friction helps fight excessive brake dust and reduces noise. Formulated as durable, state-of-the-art ceramic. Also helps prolong the life of your rotors.
