Review on Wagner QuickStop ZX986 Semi Metallic Disc by Tom Herman

I installed ThermoQuiet semi metal pads front and rear on my 03 S430 without changing the rotors just the surface of the rotor with sandpaper of the grit 220 ground . After 300 km of driving I can only say WOW! These pillows are amazing! Best bite, best stopping power, absolutely noiseless and almost lightfast. There also seems to be less brake dust, but time will tell. These should be original pads, not the Jurid or Textar used by Mercedes. For the price they can't be beat!
