Throw out bearing chirp?

I searched for it but was unable to find it. I replaced my clutch & throw out bearing about 1000 miles ago, I also had the flywheel resurfaced. The throwout bearing is chriping worse than it did before I replaced it. At the same time, the hydrualic cylinder (slave or master?) that pushes the clutch fork seems to be going bad again. My clutch pedal sticks to the floor. This is the fourth time. I do not know much about it, but are the hydraulics of the cylinder self contained or is there a resevoir? Where is the resevoir located? Why do I have to keep replacing this stupid cylinder?
