Transmission & Differential - clutch not disengaging or ?

I just bought (5 days ago) a civic with a B18c swap. Evrything was fine untill yesterday when I could not get it to go in gaer without some force. It is also hard to shift between gears. I checked out the slave cylinder and it appears to be working ok. I can't find any info on travel dems for the fork. I checked under the boot, it had some fluid in it but is not constantly leaking. Starting the car in gear with the clutch depressed it appears to start moving as if the clutch is semi-engaged/slipping. Any other ideas on checking disengagement?

is it possible there could be air in the system? bad seals?

could be a bad disc, maybe your pilot bearing......

i had a similar problem with mine. but it wouldnt disengage at all, it turned out that one of the springs in the clutch disc broke out and fell down and got caught between the clutch and pressure plate, locking them together.
