I have never tried theese pads on a Mercedes but have used them on Volvo's with excellent results. They are sold under the names of Repco, Axxis, and PBR. One of the reasons I really like them is that they do not wear out rotors as fast as some of the high metal pads and do not create the black dust that we all hate on our wheels.

I was curious too if they were available for Mercedes.
