These brake pads match the EBC part # FA158021 AD metal-ceramic and graphite iron friction material that is suitable for both dry and wet friction applications. -High static friction coefficient-Good abrasive resistance -High braking power to 500 degree celsius-The sinstered friction material is soldered to the copper coated backing plate, so Seperation (which - can happen with organic material) is virtually eliminated as a Failure risk-Low abrasive interaction with the brake rotor material-Three(3) times +/- longer operational life compared to organic and Kevlar composite Materials.
