Brake Rotors Stuck
94 with 54,000 miles has the original rotors. Would like to replace the rotors however cannot get them off. Got the caliper and caliper bracket off. Rotor won't budge. Chevy dealer did a brake job at 30,000 and turned the rotors at that time. Also discovered that the rotors are 13". Thought the 94's came with 12" rotors. Any advise on getting the rotors off would be appreciated.

i use a large 3-jaw (leg ?) gear puller and a small chunk of 3/8'' steel abt 3''x3'' at the hub center to load the outer rim of the hub...put tension on the gear puller screw (do not go 'ape' with tension which can bend/bust the rotor) and walk away...return 15 minutes later and most often the lovers will have parted, if not, add a little more tension and leave for a few...in very, very rare cases, heating the rotor at its center with the 'blue tip' has been required

I just last year replaced my rotors again. Expect to pay around $70-100 or more per rotor. There is a left and right and sometimes they are priced different. They are also directional so the cooling air flows in the right detection.
Use some rust buster and soak it.
Good luck

A BFH is all you should need. You can try squirting some PB Blaster around the hub flange ring and let it sit for a couple hours.Once the rotor is off, use a wire brush or emery cloth to remove any rust or scale from the hub flange. That surface has to be clean and smooth for the to sit properly. After it's clean you can spray on a light coat of WD-40 to the hub flange. Silicone spray works too. Make sure you wipe away any drips before installing the rotor.
Also clean the mating surface of the rotor. Most rotors come with a coating of oil or paraffin on them and while some techs clean the swept surfaces, they don't always clean the mating surface.

Thanks for all of the responce and ideas. Will try the different methods until they come off. Was going to get the new rotors from Ecklers. The Power Slot at $143.00 ea along with a set of Hawk Pads. What do you think?

That sounds like a winning combination. I just finished upgrading my rotors to the J55 option yesterday and I put on Performance Friction Pads which work amazingly. One more idea that I might add to the removing of your rotors is to buy some PB Blaster. Just soak it in and pound it with a mallet. That stuff works miracles.

back/day (many) a bud's mom was an O.R. nurse, brought home surplus surgical tubing...three feet of that and a 'selected' maple branch/fork made a super slingshot...for 'ammo' we 8-10 yr-olds would take a big hammer to the 'auto graveyard' on the outskirts of town and, with a good whack to a front hub, acquire a handful of 1/4-3/8'' steel *****...from thirty feet away, a 'good arm' could embed one of those steel ***** into a box alder tree to below the bark.
not too keen on hammering the running gear of my vette

The Tire Rack has Power Slot rotors and they are a CF Supporting Vendor. They also carry Hawk pads.
As far as swinging on the rotor and concerns about the suspension, Yoiu don't have to swing a BFH like you were going after a homer at Yankee Stadium. A 24-ounce ball peen hammer works fine. If you spray on PB Blaster and let it sit, chances are you will only need a few light strikes around the edges of the rotor.

Are you going with the powerslot because you want them?
Corvetterecycling has NOS rotors very cheap!
Sometimes just a rap at the outer edge of the rotor from the front will breal it loose.
Now before you do all that make sure there is not a washer like object on any of the studs.

Checked it out, no adapter. The wheels are American Racing and have the same bolt patern as the saw blades which I still have along with the original Goodyear GSC's. All of the great advice is appreciated. Especially the PB Blaster which I was not aware of and the 3 jaw gear puller. Will also check out Tire Rack for pads & rotors. Thanks

It's probably too late now since the rest of the hardware is off the car. But you can try braking in reverse and forwards to try to break the rotor loose from the hub. I don't like using a hammer, because until the rotor breaks free, you are also beating on the wheel hub.

You can not beat their price for a 4 rotor set NOS for $80.00 in GM boxes. I bought them and very happy with them. Also bought front and rear wheel hubs from them. They are a forum vendor.Kroil works for me when nothing else does. Spray it on and let it work itself in for 24 hrs. Use a rubber mallet if you have one.
Note that the J55 13" fronts were an option on your 94. They were std equip on my 95.
