Replaced the clutch master cylinder and the clutch still sticks to the floor and when it does, I have to put a bunch of fluid in and pump it until pressure returns. What else could be wrong and could

You may want to read bleeding instruction at this link, it may shed some light.

do you have a self bleeder kit? first off, you have to bleed the master cyl back into its self and the combination valve before you go to the wheels. when you do that, I think you will find that you have air in the lines. disconnect both brake lines from the master cyl and put the bleeder kit fittings on the master cyl, then put the rubber tubing with the kit on the fittings and submerge it in the brake reservoir. make sure its full. then pump the pedal until you get a hard pedal. if that is the case, reconnect the lines to the master, then have an assistant pump up the brake pedal with the engine off, and bleed the combination valve which should be connected to the master by steel tubing. pump it up, then hold it down, and crack the fittings loose, one at a time until the pedal goes about half way down, but do not release the brake pedal until the line is tight again, otherwise you will **** air in the lines. after you do all that, go to the farthest caliper or wheel cylynder from the master and bleed that with the same technique,and dont release the pedal until you close the bleeder screw. unless you have a major prob, this will work.

SOURCE: 1994 Cavalier -replaced master cylinder-no pressure to rear brake

The most common bleeding procedure is to bleed the ABS brake furthest from the master cylinder first, then bleed the other brake that shares the same hydraulic circuit (which may be the other rear brake on a rear-wheel drive car, or the opposite front brake on a front-wheel drive car or minivan). After these have been bled, you then bleed the other brake circuit starting with the furthest brake from the master cylinder.
Air can be very difficult to remove from an ABS modulator assembly because of all the nooks and crannies inside the unit. The modulator may have eight to 10, or more, ABS/traction control solenoid valves, plus various check valves and dead-end ports. Some ABS modulators have special bleed screws to help you vent the trapped air when bleeding the system. Others do not and require the use of a scan tool to cycle the ABS solenoids while you bleed the system. 1. To bleed the isolation valves in the modulator, there are two bleeder screws. Start with the one toward the engine. Turn the ignition on and apply light pressure on the brake pedal. Open the bleeder screw and allow the fluid to flow until clear. Close the screw and do the same at the second bleeder screw. 2. Depressurize the accumulator by pumping the pedal 40 times with the key off. Wait about two minutes for the brake fluid to de-aerate, then refill the fluid reservoir with DOT 3 brake fluid. 3. Now you can bleed the boost section. This is done by applying moderate pressure on the brake pedal and turning the ignition on for three seconds, then off. Repeat this a total of 10 times. Make sure the pedal feels firm when you have finished, and give the car a road test to make sure the brakes are working properly.

Did you bleed the system? When you replace the the master and/or slave cylinder you have to bleed the system just as you would with brakes. There is a bleed screw on the slave cylinder. Open the bleed screw, have a helper depress and hold the clutch pedal down.Tighten the bleed screw, then release clutch. Repeat this procedure until you have removed all air from the system and the clutch pedal is firm. Keep an eye on the fluid level to avoid sucking air into the system. If you have done this, remember there is a possibility that the master or slave cylinder is defective.

SOURCE: New clutch doesn't feel right.

if your sure you have gotten all the air out and all the components ie. clutch, pressure plate ect look to be ok, check the frame work that the clutch pedal is secured from (under the dash).

when they break loose, it causes the pedal to travel to far before the clutch is released all the way.
