I'm doing a all around brake and rotor replacement on my 1999 Trans Am. I get the first tire off (drivers rear) and got the calipur and calipur mounting bracket off. The rotor is old worn and very rusty. I cannot get it to budge to come off from this point. Ive tried prying it with a screwdriver in the rotors slotted edge but it broke the screwdriver. Do I have to remove a center screw of hit it with a hammer or something? Thanks in advance!

Re: Rear rotor problem
Leave the center bolt in - that secures the drive axle in the hub. Use a hammer and whack the rotor hat (the raised center section where the lug studs come through) along the edge of it, where it protrudes from the surface where the pads contact it, out toward the section where the lug studs are. Hit it around the circumference every inch or so, and see if that helps.
Some cars also have a screw holding the rotor to the hub. If your hat surface is rusty, clean it up with brake cleaner and a wire brush - it may be that you have a screw or two in there that secure it to the hub, and they're just covered with rust/corrosion/dust. If you have no screws though, usually hitting it with a hammer will break it free.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You should have an alignment on all 4 wheels. Check that the rear axle has not shifted forward or backward on one side. If you have Rear Disc Brakes, have the Hub & Rotor checked for alignment. Does this shaking happen all of the time or just when turning? Does it only happen when you apply the brakes? A Rotor and Hub that is out of alignment will cause shaking. Also check that the Caliper Slide Bolts are lubricated, otherwise the caliper will not operate correctly and the inside of the rotor will wear out faster. This can cause shaking also.
Raise and support the front of the vehicle on jackstands. Remove the front wheels.
Remove the caliper assembly; do not let the caliper assembly hang by the brake hose, instead support it with a piece of wire looped around the front spring or control arm.
Remove the retaining screw from the brake rotor and remove the rotor from the hub.
An impact driver, No. 3 phillips screwdriver bit, and a hammer may be needed to remove the retaining screw. It is fairly easy to destroy the screw slots using an ordinary phillips screwdriver to remove the tightly driven screw (see photo).
To install the disc, replace the disc on the hub, screw in the retaining screw and replace the caliper assembly.
Realize all that is holding them on after you take off caliper slider assembly, is rust & possibly rear emergency brake shoes, inside drum inside rotor. I always engage emergency brake 1 to 2 clicks then ride around the block. That gets rid of rust & ridge on drum. Release emergency brake.Jack up truck, remove tire. Spray around center of rear hub, near studs also, with a good penetrating oil. Then remove 2 retaining bolts that hold rear caliper slider to rear spindle, & remove slider assy & caliper. Now take good sledge hammer & whack center & outside of rotor. Sometimes it takes a bunch of good hits, then they come off.
jack the car take the tire off .remove the caliper ,,around middle of the rotor there is a small screw hole its is close to the tire screws you need to use a star key to take the screw off ,,that screw holds the rotor to the spindle once u take it off tap the rotor with a hammer gently to make it come lose sometimes u have to do that sometimes you don't need to ,,the rotor should come off easy ,,,replace it and put every thing back ..,,,Joe
