i have a 92 Civic DX with a B18B swap. the other day, when i got in my car, the clutch pedal sunk down to the floor, and i noticed (brake) fluid on the floor mat. i checked the clutch reservior and and it was almost empty. i refilled it and then bleed it, it worked fine. but then it did it again. and again, and again. i've been reading around and researching and i'm guessing its the clutch master cylinder. im not sure its the whole thing itself thats gone bad, it might just be the seal or something. im not too sure. i dont want to have to replace something as a whole when all i might need is a hose or seal or something. help anybody?
