Okay, what I take that to mean is the brake pedal is going down like normal indicating there is no problem in that regard. I didn't mean to imply I thought you bled the brakes. I was simply pointing out that you want to avoid at all cost running the pedal more than halfway down, regardless of the reason. Crud and corrosion build up in the two bores of the master cylinder where the pistons don't normally travel. When you run the pedal to the floor, as many people think is normal, you run the lip seals over that crud and that can rip them. Often that damage doesn't show up for a few days, but it will cause a slowly sinking pedal. This is typically not a problem yet on master cylinders that are less than about a year old.
The clutch is hydraulic but it never is tied in with the brake master cylinder or power booster. Normally the clutch hydraulic system is sealed and everything has to be replaced as an assembly, but I have found some parts available separately. I would start by looking at the fluid line and slave cylinder for signs of leakage. Even if the worst thing happened and the clutch disc flew apart, one of the characteristics of a hydraulic clutch system is it self-adjusts. About the only things that can happen are fluid leakage and one of the cylinders isn't anchored solidly and it's moving instead of pushing on the release fork.
With the rear disc brakes the parking brake cables are still the most likely culprit. Ford and GM finally went to the same simple and reliable parking brake setup that Chrysler has always used, but on your car they're still using the miserable trouble-prone calipers with the parking brake built in. If you can identify a rear wheel that won't turn by hand with the transmission in neutral, remove that wheel and caliper, then you will need a special caliper tool to retract the piston a little. The tool threads the piston in. It can't just be pushed in like on front calipers. Only turn it about 1/8 turn or just enough that you can reinstall it freely. Those pistons do not self-adjust like the front ones. They adjust by applying the parking brake. If the parking brake cable is rusted tight, you can use a large pliers to work the lever a few times to adjust the piston.
You will usually find that special tool kit at auto parts stores that rent or borrow tools. They aren't terribly expensive to buy but it's not a good investment if you're likely to never use it again.
