Our brake pads are engineered for noise free braking with dual rubber backed shims that offer 6 times more noise reduction than plain steel shims. The pad surfaces are thermal scorched for fast break-in. Evolution pads feature a true ceramic formula that keeps wheels cleaner, and won't wear-out the rotors. Power Stop pads have 20% more stopping power than other leading brands. The premium ceramic compound is made using OE positive mold technology, that assures a uniform friction density throughout the pad and this helps control noise and premature wear. Evolution pads are manufactured under TS16949 standards to OEM specifications including chamfers and slots.
