so installed new engine its running, but have no clutch. the thing is down to the floor. we bled the system, got pressure for a bit, then nothing right after. just bought a new clutch master cylinder, is there anytihng else that could be affected?
check the slave cylinder on the tranny, that will usually fail before the master does.
Either you have a leak, or one of the cylinders is gone.
bleed the system
