Hard to describe noise past three weeks. This is an 87 300D which is an occasional driver. New brakes about 8 months ago, perhaps 2000 miles on those.

Noise is a groan or scraping noise from left front. Most frequently at parking speeds with wheel turned to left. Has also happened in reverse both during braking and for a moment after stopping while backing down a steep driveway. This noise is hard to describe. It sounds like scraping, but not a metal on metal squeal sound. No warning lights or signs of difficulty braking. Any Ideas? Thanks

Try using some brake grease on the edges of the pads, but not directly on the rotor or pad's braking area. It should tell you on the little grease packet. I had the same thing happen with day old pads b/c it didn't get greased, but the sharp noise went away after a week.

Are the pads MB brand? I agree with above poster. Some shops never apply the grease. Aftermarket pads are sometimes a harder composition which can lead to noise.

Is your left front wheel rubbing the front lower part of the plastic inner fender. Mine has rub marks on it from sharp turning.
