I just replaced the front pads and rotors on my 99 E430. Based on others comments I was concerned that the rotors would be siezed on; in fact both rotors were broken around the retaining screws and so with a small tap fell off. To be specific there was a conical crack running from the front face of the rotor just outside the recess for the head of the retaining bolt through the rotor to the back so that when you pulled the rotor off a washer like piece of rotor fell out.

Maybe the retaining bolts had been over torqued or maybe the old rotors were out of spec.

I realize this isn't a big deal (the wheel bolts do the work) but wondered if anyone else had seen the same?
