I replaced my master clutch in about 45 mins. However I'm having a hard time building pressure. If I pump the clutch about 10 times, it builds up enough pressure to spring back about half way up, where it sits and then will kinda "pop" back up to its full position after a second or to. When I have someone pump it and hold, I'll open the bleeder, close it and have them release. The clutch pedal goes soft, and it takes about 10 pumps to get it pressurized about half way again.

What gives????
