The rears are different to the front. Pressed, I think...??
I'm not sure what you mean by pressed or floating though? The rears rely on the wheel nuts not the caliper to keep it straight.
Is that what you were asking?
EDIT: Glad you chimed in manny! You always know what you're talking about. ahaha
Oh, so pressed is referring to the ones that bolt onto the hub? That is like the ones in my Hyundai. Pain in the ass, you have to take the hub assembly to a shop to get new rotors put on them!
I get it now.
But yeah, I think the ones on our cars have convenient tapped holes for 10mm bolts to help release the rotor. Had to use them a few times!
