Answer
Hi there Elia;
You say you changed the clutch master cylinder, is this correct?  The clutch has a slave cylinder at or near the bell housing, at the back of the engine.  Is that the part that was changed?  The slave cylinder needs to be "bled" after being replaced.  There are little air bubbles, and air pockets in the line that comes from the brake master cylinder via a small tube to the clutch slave cylinder, and those little bubbles, and pockets of air are "compressible," unlike the brake fluid.  So, if you have some one sit inside the car while you use a wrench to release, and retighten the bleeder screw on the end of the slave cylinder, you can bleed all of the air out, and make the clutch release, and get some resistance, and "feel" back into the clutch pedal.
When you are ready to open the bleeder screw, tell your partner to push down, and hold the clutch pedal.  At the very same time they push in on the clutch pedal, you need to open the bleeder screw, and while they hold the clutch pedal, you need to tighten the bleeder screw.  Use a little piece of vacuum line, and an empty plastic soda bottle to catch the fluid, as it comes out.  Just repeat the push, release, hold, and tighten method until your partner says the clutch pedal has some good "feel."  Test it in between tightening, and opening the bleeder screw.  I'm sure you'll have to repeat the process a few times,  and make sure you add fresh brake fluid to the reservoir every other time or so, or you won't have any brakes when you are done with the bleeding of the fluid....it will all run out, so have a fresh pint, or maybe a little more on hand to make sure the system stays full.  Once you get started, you'll get the hang of it, and you'll have a clutch that works too.  Good luck, Elia...I hope this is of some help to you.
