bolts

I couldn't spin my front wheel properly ( rotor gets caught in the pads ) so I loosened off the brake caliper mounting bolts, and it spin's perfectly.. How should I fix this ?

gday, guys and girls. im trying for the life of me to remove the bolts out of the old set of hubs, i cant seem to crack the bolts, i dont want to snap my allen key, or damadge the bolt heads them selves.... any ideas?
