My passenger side front caliper piston is frozen and that brake is getting no fluid at all, what the heck is going on?!? I also have a rear brake line out (it's cut, i'm not sure if that would have anything to do with it) Someone please help me!!! I'm new to the brake systems on these! Also my car has 4 wheel disc...

 

A very common problem in these cars. Usually it's the brake line rather than the caliper. Look at your hose to the caliper, should see a metal ring about in the middle of the hose. This seems to be where the hose deteriorates and swells together inside, blocks flow of brake fluid both in and out of the caliper. Need to replace hose and bleed air from the line.
