Answer
    You're saying that you push on the pedal and it won't move?  That's not the master or slave cylinder, it's something mechanical.  First check under the dash and make sure that something's not fouling the pedal and keeping it from moving.  Then you will have to check under the car and see if something's fouling the arm that the slave cylinder is pushing on.  Disconnect the slave cylinder and run a wire-tie through the eye on the end so that it won't come apart, then try giving the pedal a small push.  If you find that movement has returned, then the problem is in the bell housing.  The throwout bearing may have become bound up on the sleeve that it rides on, or it may have moved beyond it's normal range of motion because of a clutch failure.  Unless you have a well-equipped home garage you will probably have to get it towed to a mechanic.
    If you, on the other hand, mean that the pedal is resting on the floor, in the position that normally means you have already pushed it all the way in, then it probably is a hydraulic problem.  Examination of the system (slave and master cylinder and the lines that connect the two) for leaks would then be in order.  If it is a hydraulic problem, I would recommend replacing the whole system, including the lines.  Clutch fluid is identical to brake fluid and can be highly corrosive.  If it has caused a problem in one place it is probably getting ready to cause a problem somewhere else.
