Brake disc/rotor stuck on hub due to rust
Discussion
As others have said, heat is usually the solution here. Use plenty of penetrating oil (better than WD40 for this) put your gear puller on and apply a little tension to it. Heat the disc uniformly with your Propane torch and get it plenty hot. Apply a little more tension on the gear puller and it should release. If seriously stuck use a combination of heat and cold - apply icecubes or a freezing agent spray to the hub and heat to the disc, job done!
If you don't need to save the disc just belt it with a big hammer till it surrenders!

Are you whacking it off or on? Try whacking it on if you haven't. I assume there isn't a retaining screw that you've missed?
didn't exactly whack it but hammered it in both directions from front and back with mediocre force. We did this for an hour while taking turns but it refuses to come off. There was also only one screw and I took it off.Use the mallet "around the clock", whack it at 9 then 3 then 6 then 12, repeat until it gets bored and comes off
I had a similar problem and penetrating oil, heat and whacking it simply didn't work. I had to turn the steering to get access to a small section of the rear of the disc, then use a dremmel with a small grinding wheel to remove the rust lip a bit at a time.
Horrible job that took virtually all day, but luckily, the drivers side just fell off with no trouble.

had all 4 discs renewed on my car last week. the local garage said it turned out to be one of the hardest jobs they've done- same problem- front disc stuck to hub.
chap told me they cut the disc into 4, pie shaped pieces to get it off. I guess they had many tools to hand to try first too, like pullers etc.
I was delighted- I'd priced the parts up and thought of doing it myself (I was a mechanic donkeys years ago for a bit) but I genuinely can't be bothered now- it only cost £100 more for the garage to do it, plus day off work and the hassle. as it turned out, a lucky decision.
good luck.

I had this trouble some years back and after copious use of PlusGas I was worried that if I hit it any harder with my lump hammer I'd knock the car off the axle stand. Gave up and took it to a garage who spent a while belting it with a much bigger hammer before using angle grinder to cut a slot in it and then chiseling the thing off.
