Quoting Gilga5:
Well I cant believe I Missed that smh. It is Hydro. I will check to see if the fluid is low.
Have an accomplice safely operate the clutch (engine off/park brake working and engaged, wheels chaulked on a flat surface.
Confirm you have the slave cylinder moving the slave rod going into the bellhousing through the rubber boot.
If no movement, best to replace the slave and master with reputable parts like OEM or quality aftermarket (find NABCO in the pictures on RockAuto or at a local auto parts seller).
If the fluid is original also, god knows how old it is and would be full of moisture and that in combination with the rubber degrading in the hydraulics, you have a recipe for worn out parts.
Dot 3 fluid should be used as it lasts longer between necessary fluid changes than DOT 4, as was original spec for your car.
If you have a pop around the forum, there are some in depth versions on how to bleed the new parts once they are in place.
If you do have movement of the slave rod in the proper distance from a center located fork finger in the bellhousing opening, then we have greater issues but without more detail it is hard to say.
