Best way to break a fused Brake Rotor loose?

Hi,

2001 Suzuki Grand Vitarra XL-7.  Rotor is worn out and appears to be fused onto the wheel (Rust?).

What is the easiest way to break it loose without damaging the SUV?  Would putting the wheel back on with loose lug nuts and lowering the jack while turning the wheel work?  Or might it damage the car.  I am old and don't have a  lot of strength anymore.  Best ideas would be welcomed.

 

Thanks,

Dennis

Use a small propane torch to heat up the rotor and give it a quick whack with a hammer. You can also do this.

Stick a bolt through a caliper mounting bracket hole. Size the bolt so it will touch the back of the rotor and put a few washers on the rotor side of the bolt, then thread on a nut. Tighten the nut with a crescent wrench until the rotor pops off. I've never found a rotor that can't be loosened with this trick.

Common issue, but not usually an easy answer. I wouldn’t lower the car to loosen it. You can try @justin-shepherd ideas. But I think the best way to avoid unintended consequences is a rubber mallet+sweat+patience. 
Then when you install the new rotor, coat the interface with a touch of anti-seize to make your job easier next time.

That's what I would do.

If it still doesn't help, you can rock the vehicle side to side a bit too, or even drive it a few feet. Just make sure to keep the weight on the hub.
