go to advanced auto and "borrow" there serpentine belt tool set, and purchase the correct socket to fit the big bolt on the caliper in 1/2in drive. (22mm??)
that tool kit, when put together gives you about 4 to 6 ft of cheater bar, mine turned like butter. the handle was out past the front bumper.
you have to pay for the tool kit, but when you bring it back they give you the money back. that is the way there tool loan program works.
make sure you have a ratchet that will turn the socket you bought. the tool doesnt have any rachet action, so once you loosen it, you switch to a regular ratchet and take it off.
