Well, today I got the parts in for my 300E, couldn't wait to get off with work and put them in to see if I could finally drive her again without issue. Got home, opened the box, everything looked good and I went to the install. I had to get the metal post off the old rotor arm since the new one didn't come with it. The three bolts holding it in would just not budge and were stripping, sprayed tons of nuts off and it did nothing.. I tried the manual way with a grip wrench and it only cracked the plastic it's in there so tight. MASSIVE disappointment... The car gods just didn't want me to repair today... Called Mercedes to see if I could order the parts so they could be in tomorrow. I'm told parts just closed at 7... look down and it's 7:02 But I noticed the ceramic? plate that lies against the metal backing has a crack in it.. Not sure if this will affect the performance, but something inside me tells me to just get a new one just to be safe... Should I or is this something that wouldn't affect anything? Please see pictures below.. Hoping to have her going by Thursday
