When EBC broke into the sintered pad market they really did their homework. EBC took all of the current market offerings, tested them, analyzed them, and beat them. The iron powders commonly used in many other sintered pads were removed due to the likelihood that the pads may "weld" to the disc because of corrosion. EBC replaced those materials with a stainless powder and removed several other particles to prevent disc damage. After 5 years and millions of sets sold, EBC upgraded the formulation again due to the development of SB101C material which completely eliminates brake noise, improves the head cycling, and provides a good feel. What EBC has today for the faster rider is the pinnacle of sintered copper alloy engineering. *** ECE R90 approved. Cheap and nasty motorcycle brakes are the quickest way to an accident no matter where or how you ride. This is why EBC Brakes welcomes the new legislation on ECE R90 brake safety testing that shuts the door on unworthy parts.
