I need some advice: first some background.1986 CJ-7. I converted my mechanical clutch to a hydraulic clutch about four years ago.
Everything worked great until last week when all off a sudden, I have no clutch pedal. The pedal went all the way to the floor and the clutch does not depress. I looked at the master cylinder and all the fluid was black, and it was seeping out of the bore down both sides of my firewall (engine and passenger compartment). Ok, so a bad master cylinder (I thought).
I buy a new one, bleed it, and it works fine for about a day. Then the same problem. No clutch pedal, but no leaks. I figure it must be air in the line. Bleed it again and everything is rosy for about a week. Last night I come to a stop sign.NO CLUTCH, WTF!!!!
I bought a brand new master cylinder (not rebuilt) so I'm hesitant to blame it. I don't see any leaks in the hydraulic line. Is the system sucking up air somehow? If it sucked in air, wouldn't the reverse be true i.e. it would shoot out hydraulic fluid?
The slave seems to be fine. No leaks.
