http://www.extremehowto.com/xh/article.aHow to take off front rotors on 1997 GMC Safari?I don't know what it would be like for that car, but there should be something holding the calipers in place, possibly a bolt and some metal pin you need to hammer out. Then behind a grease cap there is probably another nut.
Depending on the kms, you could think about changing wheel bearings as well (they are easier to get at with the rotors off).
I could be way off for your car- I just did my first rotor job on 1977 ford.
