well, i have a '93 but it is to the best of my knowledge that the 90-97 share identical suspension parts.

the rotor bolts to the back-end of the hub. which is then pressed on. but the rotor itself is not physically pressed on (not sandwiched in between).

there are a couple of ways to do this. you can take it to a mechanic and have them use a press and disassemble it for you. or the other way is to hammer out the entire hub from the back end and you can then remove/unbolt the rotors that way.
