Just replaced clutch, pressure plate, throwout bearing, and fork.  I'm sure the clutch is not in backward.   Bleed the master and slave cylinder and can see travel of 1 3/8" at the slave cylinder, but the clutch won't disengage.  Has anyone ever experienced this?  Is the master cylinder adjustable to get more travel at the slave?  Does anybody know how far the clutch slave cylinder should travel?  

Slave cylinder travel should be about an inch to inch and a quarter. That part sounds fine.

 

Is there resistance when you push the pedal? Does it push back up all the way on its own?

If you put the car in gear, push the clutch in, and then try to start it, does it try to jerk the car forward or does it start normally? If you crush the pilot bearing on installation it can create enough drag to keep the transmission from shifting into gear, but not enough to move the car.

 

Otherwise, if you can see the fork moving and it isn't disengaging, it might be the clutch disk in backwards, even though you swear it isn't... Did it say flywheel or engine side on the hub anywhere?
