please help - Bad Master cylinder?

[Kalypso]

Hello I have a redtop that is freshly swapped into a 90 coupe.

hm, i think my master might be finished.

I deleter the dampner box and Im working around it.

I added fluid and bled the slave, as i was pumping I noticed that I was getting a little more pressure on the pedal. and fluid was squirting out of the slave bleeder valve. but once I tightened it and filled the master cylinder again it still doesnt give pressure.

its at about 15% strength.

and I have to pull the pedal back up, after I push it down.

ok I had a break through which leads me to believe that my hardware is working fine, but the clutch pedal is still lacking pressure.

I continued to bleed the slave.

and the pressure from the clutch pedal kept increased little by little.

at one point, i closed the bleeder valve, pressed the clutch and it pushed back with lots of stiffness! then gave way, like it didnt have enough strength.

im all out of clutch fluid because i bled more then I was supposed. but this event may be helpful in diagnosing my methods.

I am doing something wrong but I dont know what it is.
