cannot remove bolt on caliper
 

i was doing my brakes on my 06 civic sedan lx, so i did the driver side first and everything goes fine. i proceed to the passenger side i remove the top bolt on the caliber, and notice it was very difficult to remove, but i got it off. then i proceeded to the bottom bolt and it would not budge. i worked on the one bolt for about 2 hours and no love.

anyone have this same problem? or just any info at all
