Rear rotors rusted to hub :(

Bought a used stoptech bbk, no problems installing the front. The rear rotors are frozen solid to the hub. 3 of us beat on it for over half an hour with not a wiggle. Does anyone know any tricks to get them off?

Do you have the parking brake set? I had this problem one time and it took me awhile to figure out that I had the parking brake on

I start with a 3lb dead blow hammer and work my up. Usually after an hour and a 5# engineers hammer, I've broken it loose. Sometimes ruining the rotor.

Have you used lots of WD40 or other penetrating oil to help loosen things up?

I learned that one last week on my friend's 525. Good to know the e-brake works.

WD-40 and a dead blow will work.

How about applying heat to the rotor hat (not the hub)? Should cause it to expand at a faster rate since it's thinner.

Today, we used a hammer and tapped it on the hub (between the studs). Soon after the rotor finally came off!

Idk if heating up the metal (to the degree a torch would) is such a good idea. That kind of heat can change the composite and properties of a metal and it's probably ill advised around brake or wheel parts as it might make the metal more brittle.?
