8x1.25, to be exact. And rattling the rotor with a few good shots to the 'hat' section of the rotor with a BFH is the preferred choice of most techs. Just don't hit the studs, the working face or the center of the hub that protrudes through the rotor. Being in NH I'm guessing that there's a fair bit of rust so a good spray of WD40 or similar will also help. Just don't try to remove with the bolts only, whack it a few times to shock it loose. If you don't you'll probably just pull the threads out of the rotor.
