Brake question... yes im a new B.

Ok, I have done an intake manifold install by myself (ok, my younger brother helped some). Pulley's intall by myself, everything in my sig, except the gears where done by Ford.
Now this is my first time ever doing brakes, and im having troubles changing them.
I have the t-50 star wrench, and am TRIENG to turn it counter clock wise, but it won't turn at all. Am I suppose to disconnect anything else before I turn it ? Or does it seem that I need a lil bit more muscle to turn that damn bolt. bolt.

After that I guess, im going to have to do some schimming on those rotors.
