Ok, yes, you are correct - I got confused by some of the info -- had it right originally -- the parts I am trying to loosen ARE the caliper BOLTS. Such as (on the right):

Those bolts aren't known for giving the kind of trouble that you are running into. They'll be pretty tight but not knuckle busters. Also, the ones in the picture have a decent sized head (are yours different than those pictured?) It is more often that those sliders in your picture get frozen and can give you a real headache. You can use the prying back and forth between the pads and rotor to get an idea ahead of time whether or not one or the other of these sliders is frozen. Or, for example, while it is all still assembled, pry on the pad that is on the piston side to push the piston all the way in. Then get in between the back of the pad and the piston and pry that piston in until it is fully seated (something you'll need to do when replacing pads anyway). Now you should have plenty enough room to move the caliper body back and forth on the slides to find out what further trouble you might encounter. Obviously, if the piston won't retract, you need new calipers. If the pin, or pins are frozen you might work them free with heat applied to the caliper bracket.

Those pins should drive out. The bolts, on right gold color, look to be what holds the caliber to the bracket. I’m thinking you should be able change the pads by just driving the pins out and leave the caliper mounted. Maybe not, as I said before I’m a GM guy.

Forgot something, if you really need those bolts out versus just the pins, I would bet the bolts were installed with lock tight, heat is definitely your friend when dealing removing bolts that have had lock tight applied, especially the red stuff.
