A good metric socket set, penetrating oil, and a big hammer. Actually, an impact wrench is the key. Keep in mind that the caliper itself is held on by 2 bolts to the caliper bracket. And the bracket is held to the car by 2 other (I think larger) bolts. The 2 that hold the calipers to the brackets are loosened every time you change pads and therefore are usually not as hard to remove as the 2 that hold the bracket to the car. Not only that, but these 2 bolts have what look like washers on them but these "washers" are actually part of the nut. This gives them a large "friction" area. And this friction area has ridges or grooves on it so as to sort of "embed" themselves to whatever they tighten up against. So don't try removing them with steady pressure, but rather a "beating" motion. An impact wrench would be ideal. You will require a 15mm socket or wrench for the caliper slider bolts, and a T60 torx for the bracket If your doing the rear you will need 18mm wrench
You replace them. It's quite simple and involves only removing the brake caliper and caliper mounting.
I have an 01 Deville, which I just replaced the front rotors. Not sure if you need to replace the front or the back rotors...for the front it's easy. After you've removed the tire(s), remove the caliper from the bracket. This is done by removing the 2 bolts on the back of the calipers. FYI, all the bolts back there are 15mm. They're on there tight, so use a breaker bar. Once you've removed the caliper, you need to remove the caliper bracket in order to remove the rotors. The brackets are held on with 2 more 15mm bolts on the back side of the brackets. These puppies are on there! The bolts are installed with loc-tite, so you'll need to whack each one before you start cranking on them. After you've removed the bolts, the brackets will come right off allowing for you to remove the rotors.
see the answer for removing rotors. stop before removing the caliper carrier. very simple.
Remove the wheel, locate the Caliper. On the inner side there are 2 bolts going through the caliper, remove those (before removing use a flat head screwdriver to compress the caliper some) remove caliper. If you are removing the rotors remove the 2 large bolts on the caliper bracket.
if the caliper is stuck u need to replace the caliper it is also a wise move to buy a matched pair of calipers, cheaper , and replace both sides at same time
You will need to remove the tire and wheel. You can remove the brake pad and break assembly, by removing the brake spring and caliper. Loosen the rotors with a hammer. The rotors will slide off. Reverse the process to install the new rotors.
Remove wheels Remove 2 caliper mounting bolts Slide caliper off rotor and support Rotors should slide of wheel hub I posted this question originally and just finished changing them. I had difficulty removing the rotors (after removing the calipers as noted above) because they had rusted to the axle/wheel mount. Consequently, although it was a small bead of rust--I had to first heat the rotors with with a small propane torch and then beat them with a sledge hammer to break the rust bond free. Then the just slid off the lug bolts/wheel mount. I ended up replacing the rotors instead of having them turned.
when you remove the caliper on the disk brake by removing the bolts on the inside of the caliper the rotor just slides off, the only thing holding the rotor in place is the wheel.

the brake rotors should slide right off after you take the caliper off.there should only be two bolts inthe back of the caliper. take those out and the caliper will pull off .then the rotor should come off.
1. jack car and remove wheel 2. remove the brake caliper and pads by removing the two bolts holding on the caliper 3. remove the mounting bracket for the brake caliper by removing the two bolts attaching it to the spindle. 4. pull the rotor off
