Buy a seal kit from autozoe, wil cost you around 17 dollars. Remove clutch aster cylinder by firstly undoing the resevoir clamp and remove the reservoir to give you access to the hard hydraulic line and detach the line. Undo the two bolts holding the master cylinder to the firewall and then go inside the car and pull the cotter pin holding the end of the mastrecylinder plunger to the pedal (watch the washers and remember how they go back on). Remove the unit, and strip it down to replace the plunger and releif valve you get from the kit. Good Luck.

You've replaced the master, the slave, now I would check to see if the throwout fork will move by hand. If you can move the fork by hand I would say that your pressure plate and or throwout bearing are worn out. First try to just gravity bleed the system. If that doesnt work, it may be time for a clutch, pressure plate, and bearing. The pressure plate spring pushes the pedal back up and depending on how many miles and driving habit those little arms on it break off and just wear out. I hope this helps you.

its called a clutch fork,and you need to pullout the gearbox to replace,its worth keeping the car if its a good car in general,shouldnt be too hard to remove gearbox,maybe a good mechanic can repair the fork in the car....eg;weld it
