Rotors and pads appear to be of good quality. Everything went well on install. About 300 miles in, the brakes are still a bit grindy sounding. The pads had abrasive outer coating for use on old rotors I assume. Get that wore off and I'll see if brakes quiet down. They work good. Car stops good, and no rotor vibration. Rotors show no uneven wear. See if they stop grinding noise. If noise stops soon, I would buy again. Place of manufacture is a bit unclear. Box said British product, that all.
