I know this is a very old thread, but I have to comment. I have a clutch problem which is why I searched. The last poster (3 years ago) says that the clutch and brake cylinder are the same thing. This is WRONG. The clutch and brake RESEVOIR is the same, but there is a seperate clutch master cylinder, drawing fluid from that same resevoir. Replacing the brake master will do absolutly nothing for your clutch, at all.
That is all
