Driving me nuts hearing my brakes grind when I knew I had a lot of pad left. I went ahead and bought some new ProStop Ceramic pads (had them on my 626, great pads) at Pep Boys. Pulled off the old pads and this is what I found on the right front:
It appears whatever metallic material used was causing some very light grooving in the pad itself-you should be able to see it in the top part of the pad. Didn't seen any problems with the rotors.
No idea who made the pads on the car, they have an "AM" stamped on them. Anyway, I bedded in the new brakes and stopping is now grind free.
