THANKS for all your advise. I replaced front pads and left rotors alone this time.Next time , if needed, I ll just replace rotors, but thats along time off as I have over 35K on original front pads.Every MB owner sholud read these posts, especially the link from Mikes post. (PS. brakes feel great, very easy on new e class).
