'90 300e 4matic front (brake) grinding

Recently, there has been a distinct metalic noise which comes from the left front side when the brakes are applied on my 300e 4matic. As the car slows to a stop this noise becomes more grinding in nature, as if the pads are totally worn to the metal. I checked the pads, which I've recently replaced and while they have plenty of pad material on them, I noticed 3 small areas where material appeared to be black and gritty. I also noticed that the rotor surface appeared slightly elivated/depressed, possibly related to the distorted areas on the pad. Might the pads be causing this problem? Or is it possible that the brake loading of the left front is causing a wheel bearing to make this noise? Thanks; Dave
