My tech uses Texstar pads on Mercedes. They have a "soft" backing plate so they don't vibrate against the piston. I've never heard a peep out of Texstar pads.

BTW, if you are inclined, changing pads on a Benz is almost as easy as changing a light bulb. See the FAQ on the subject, you will save about $100.
