1999 Mitsubishi Eclipse clutch pedal goes all the way down

thanks for the post.. under the hood near the brake master cylinder is a small cup like clutch master cylinder, with a small white round cap. dot 3 brake fluid goes in there. you may or may not know all this.if its low on fluid, fill it. also there is a clutch slave cylinder with a bleeder screw attatched to it. this is where you bleed it to get a full pedal. takes two people. one pumps up the pedal & holds it down, while in the down position the other person opens the srew, lets air & fluid come out & closes it back , now while the cl. master cyl is way up high, the clu. slave cyl. is way low between the lower part of the radiator & the transmission bellhousing. a fluid line runs from one to the other. you can do this. with help. afterwards clean all access fluid to check for leaks in the future . if no leaks r present you have a faulty clutch master cylinder or slave cylinder . please let us know how u proceed & what happens. thanks.

thanks before for the help, i did as you said, and the pedal worked as normal for a couple of miles, eventually it did the same as before and now is in the same condition, i am going to purchase a new master clutch cylinder, but before hand i would like to know how difficult would this be, and could i get a simple walk-through of the procedure. Will donate next time. SERIOUSLY THANKS. :)
