Holy cow! You guys solved my problem......Actually I am a little embarrassed to tell you the truth.....I just found out I had the parking break on.....I didnt know the parking break was set up almost like a drum break under the rotor.....I even have a mercedes CD fix manual, and I couldnt find any information about this problem I was having....Once the parking break was released, I could have taken the rotor off with two finger tips. Whole time I was thinking the rotor was seized......Wish I would have check here earlier....My car has been up, and wheel off for almost a month now.....How stupid is that? Thanks!!!
