So my wife's 2000 2.5 RS drives fine for her but when i drive it the clutch pedal slowly starts to stick and eventually sticks to the floor and if she begins to drive it again it goes back to driving fine and the pedal returns normally for her. i checked the fluid level and it has not changed any or might be slightly low but i also watched the fluid levels and there was no leak visible. It doesn't seem to have any kind of air in the system or it should do it to my wife as well right? I will be looking at the pedal assembly later but didn't know if anyone else had this type of problem as well and could help before i start lubing up everything and then take it to a mechanic to rape me. Thanks in advance.
