Brake Rotor stuck really bad
Ok here's the story. I changed rotors, pads and hardware at 3 corners with zero issues.
On the 4th corner, the damn rotor is frozen to the hub. I tried bolt after bolt in the center hole thats supposed to force the rotor out, but all of them strip after they contact the hub. I dont know if I'm using the right sized bolt? Its a M8 x 1.25 mm (I dont have a spare tiedown bolt that people normally use here).
Then I tried wedging the jack between a piece of wood supported with the chassis, and the rotor. No go.
Went to autozone, rented a 5 ton 3-jaw puller and used that on the outer surface of the rotor. Damn thing didnt budge a hair, so I heated the rotor with a Bernzomatic, and I ended up separating the rotor surface from the boss that holds it in place. Kinda like this (THIS IS NOT MINE):

Now the rest of the rotor is still behind the rotor boss and I don't know how to get the boss out.
Help me out with suggestions, guys???

Find someone with an air hammer or see if any hardware stores rent them, I run into that problem often at work, and on the few severe cases like yours, the air hammer gets it off fast. Or just take a flat chisel and try to get between the hat and the hub if possible. Like others said PB blast the hell out of it. It will come..

Air tools or tools of any kind that make noise are out because I live in an apartment. But a hammer is ok. I will try all of these in turn till I get it out. I already gouged the driveshaft face pretty bad with the puller bolt.

Not trying to be condescending here, just clarifying, but by "hammer" or "BFH" we don't mean your typical framing or woodworking hammer. Not heavy enough. You need about a 3-5 lb mallet. Spray the rotor-hub interface liberally with PB Blaster or the like and let that stuff work overnight, and it should pop off with a couple of hits.
