Alright. Been trying to replace the rear brake rotors on my parent's 300E for the last couple of shop days. I have searched the threads, have smacked the face of it countless times with a 2lb dead-blow hammer, have soaked the rotors in penetrating oil to the point where oil is weeping out of the bolt holes at the hub/rotor interface, have smacked it from the backside almost as many times as the front side, and STILL the rotor will not budge. The parking brake is off, and the allen screw is out.

It's almost like someone epoxied it to the hub.

Thanks in advance,
Anthony
