Rusted on center hub.

Squirt a little wd40 around the hub , tap around the center and edges with a hammer and try yanking it back and forth .

Are you replacing the rotor or plan on putting it back on? If replacing it anyway, penetrating oil (blaster pb...ftw) and brute force with a hammer close to the edge of the rotor. Spin a 1/4 turn, hit again, rinse and repeat.... hit it from front and back. If you are reusing them, then you must be more careful. Use the oil, and of you can find one, a brass hammer. Same technique as before, but lighter hits and more of them. If your aim is good, a few hard strikes at the rotor near the studs can break it loose too... just dont hit the wheel studs....

Thanks for the info. Did all that. And it got ugly from there. I had to drill holes in the rotor at the edge of the hub to free it up. I'll post some pics. later. But it did come off.

I was going to say that sometimes heat from a plumber's hand-held propane torch will do the trick. I would have tried that before drilling. Glad you were able to remove it.

But what was the cause so we can all try and avoid rusting on our S197s.
Park it in a creek for a few months?

?? only thing I can think of it's my daily driver in CT. Winter driving? And it was the right rear that was stuck. The fronts had a lot of grease behind the rotors. The backs had none.
