I pounded on the old disks, heated them up, lubed them and those bastards will still not budge, I assume that they are rusted in place but I would like to know if I am missing something.

You need to heat them up more. You'll probably need something more then a propane torch, MAP Gas or an oxy acetelene torch.

I did the brakes & rotors on my old boss's eclipse. Had to use an oxy acetelene torch. I banged on those things for a while before doing that.

You need to get a BIGGER HAMMER and hit the center area of the rotor.
I have done hundreds of brake jobs and never had to use heat.

Maybe a little WD40 on the hub area but never had to use heat.

BTW...when I say bigger hammer I mean like a mini sledge hammer.

First, if you're talking about the rear brakes, make sure the parking brake is off.

Then, get two M8x1.25 bolts. The brake discs have threaded holes in them for exactly this purpose. Thread them into the holes evenly until the discs pop off the hub.

Yeah, I made a puller for doing mine...out of a piece of flatbar and 2 bolts...took all of 5 minutes...and works great

+1 - works perfectly.

I used the bolt trick on my rear rotors this summer and it did the trick perfectly.

My rotors don't appear to have these holes, which kind of stinks.

So I guess I am back to heat and hammering.

I can't imagine what Chinese junk (the cheap crap, not the boats) wouldn't have the holes. Spray the hell out of it with some good penetrant - Zep is the best, but PB Blaster is easy to find and let it sit for a day or two, maybe reapplying a few times in between. Thread a lug nut or two on the bolts and whack it as you rotate it from the back. Bearings don't like heat, so be careful going that route.

It's not a bad idea to put some grease on the back of the new rotors to keep them from bonding.

i did the same thing. much better then risk warping other components with heat or weakening them.

Purchased

2 x can "3 and 1" Penetrating Lubricant (in the orange can)
1 x 4lb sledge hammer

It dawned on me that if I were turn the wheels that I would have a better vantage point as the car is not jacked up too high. If you feel behind the disk there is a ring of teeth that match up with the hub. I sprayed a lot of the lube in there over a two day period. Then I pounded the perimeter of the disk with the sledge. Then I gave it about 20 good wacks on the back while rotating the disk. Then hammered one side of the front until finally I saw it move.

So I again started rotating the disk while hitting from behind and then it finally came off.

God love the sledge hammer, it makes a man feel mighty.

I am including some before and after pics (they were taken with my phone so the quality isn't all there.)





This picture is blurry but you can still tell what I am dealing with



No wonder it gets corroded the hub isn't solid. Water and salt have an open door. I wire brushed the hub down then I coated the perimeter with anti-seize. I shouldn't have the problem again.



Here is a close up of the corrosion in my disk, it's way worse than what the picture displays



Here is my new disk and pads, I am a happy man.

AHHHHH!!!!!!!

The spoils of sucess.

Looks good!!

Ack, your new discs also lack those threaded holes! Didja put antiseize on the hubs?

Hahahaha. I hate it when that happens.

The rear disks have holes.

I would only do this as a last result, banging that hard on the hub can do bad things to a wheel bearing.

That's funny because I've been doing it for 25 years and never had any trouble

Guess your lucky then I've seen it happen a couple of times, all be it on newer models but still.
