The first couple of times I use it, it works fine & then it will not disengage. I've already replaced slave cylinder & bled several times. It still seems to act as if it has air in the line. Any help would be appreciated. | | |

Sometimes this hose will also be weak from age and collapse partially as pressure is let off the clutch pedal. Don't bother looking for a replacement, there is none. You need to find a piece of ready made brake hose that has the 1/4" npt female fitting on each end to use as a substitute. Also check to make sure that the hard line going over the bell housing didn't get kinked when you were replacing the slave. HTH. | | |

I had some luck using a hand pump oil can with a hose on the end. Filled it with brake fluid and opened the slave bleeder and pumped fluid up the line to the master.

It is a B---ch to bleed that slave. One other problem I had, that could be related to your predicament, was a WEAK return spring that did not pull the clutch fork back firmly when pedal pressure was released, that left the clutch engaged a bit longer than it should have. Added another spring, problem solved. | | |

Air likes to travel upward.
