From what I've heard they are pressed on.

The last time I serviced my brakes I'm pretty sure I just yanked the rotors off after undoing the calipers. They should come off pretty easily. I don't remember anything tricky that gave me any hassle.

just tap the back side gently with a BFH (alternating location of taps) and it should pop opp.

use heat around the two locking screws on the mounting face of each rotor and remove the screws when the area around them is hot and has expanded. once the screws are out, remove the caliper and bracket and remove the rotor. if need be you can tap the rotor with a hammer. use a rubber mallet or soft dead blow hammer so you don't damage the rotors. whoever told you the rotors are pressed on obviously does not know what they are talking about.

An impact screwdriver like this: http://www.google.com/products/catal...d=0CCwQ8gIwAw# works wonders on those stubborn screws. If the hub is rusty you may need a puller.

Ditto on the BFH mentioned above, as well as heating the phillips screws to get them out. Mine had been setting in a field for 17 years, yes years not months, and they were really corroded onto the axles. If they are really bad you could shoot some rust blaster or something like it into the holes, after you pull out the screws, then as they give a little, another blast or two in each hole to finish breaking them loose. Be sure that you get it between the end of the axles and the rotors.

When you heat them up, listen for a distinct ping sound. That sounds occurs
when the expansion from the heat causes the surface corrosion to break apart.

Persoanlly I've never had an issue with any cars rotors like this but with drums
its very common.
