Tips for Freeing stuck Brake Rotor

it's on a ford 8.8 so far I've soaked it in WD40, hammer'd, chisel'd, torched, pryed, etc. and the sucker is still frozen/rusted to the hub/axle shaft

get a really big hammer, and hit it till it brakes!! no joke... did a set of brakes on a neighbors contour and thats the only way it came off.
 
I've found that taking a good heavy hammer and fetching each of the wheel studs a good, sound whack will usually loosen rotors up - follow up with a drift to the axle shaft hub, if necessary.

The inertia of the rotor will make it want to stay put when the axle shaft moves, which will usually start to break the rust loose...

In severe cases, I've found a wire "end" brush chucked into a drill motor seems to help break crud up as well - apply, and repeat impact as indicated.

PB blaster, heat, whack; repeat as necessary. put the lug nuts back on the studs before the whacking so you don't end up ruining the threads......

That could work, but heat just the rotor, and not the axle shaft. That will make the holes larger (by a couple thousandths - but take what you get!) and the rotor is a lot easier to replace than the axle shaft...

On the junkyard 8.8 we put into a buddy's TJ, we ran into the same problem. the easiest fix would be new shafts and rotors, randy's does have the sweet clip kit. But we ended up, after a few choice word and not have a hammer big enough, cut the top hat off the rotor (please do it outside and wear protection), then air chiseling it off the flange. The second one went hella quick. Would have love for them to just pull off, but take what you can get.


THIS IS WHY KIDS, ANTI-SEIZE IS YOUR FRIEND.

Say it with now with me kids, "ANTI-SEIZE".
 
Not a solution to your prob, but I noticed this past weekend on my GF's Nissan Sentra that their rotors have 2 threaded holes where you can screw in a bolt to push against the axle to pop the rotor off if it's stuck. I was afraid to wail on her rotors with a hammer, so I looked in my box of bolts and actually had the right size. They came off easily. All rotors should have that feature.

problem with that is in the rust belt the threads rust in the holes. Tried it with my Escort once, rusty threads just came out of the hole and the rotor went no where.
Commence with whacking.

Yeah, I was thinking the same while doing that. Her rotors had spent the last 2-3 years in upstate NY and the threads looked pretty bad. The bolt held though...lucky me.
 
front or rears? if these are rears make sure the little e-brake in side is not the problem.
