I had a hard to remove rotor earlier and saw this video after trying to hammer it from behind, this did the trick:  

Quick question, is the low pad sensor on the inside or outside of the disc brake?

On floating caliper systems, I think they should go on the inside?

 

maybe check drawings at www.opposedforces.com?

Yes, that's how I did it; I checked out one guy's vids. on it and it looks like it is on the inside.  

I got seasick before I got to the point of that video....

Looks like we're talking about the threaded holes in the face? Yep, those are present in the front, and most quality rotors for most cars. My problem is by the time I need them, they're too rusty to use. I tried it on the rotors from our '04 Outback since I had hoped to use them again, and stupidly used caliper bolts to do it. Not only did I not get the rotor off that way, I wrecked my caliper bolts....

 

The real secret is backing off the parking brake shoes through the little access hole in the backing plate.
