Ok I’m stumped and so is my boyfriend I have a 1992 Honda Civic LX. Was driving the other day and at random started losing pressure in the clutch before I could get home pedal was on floor… so we replaced the clutch master cylinder, bled the system and test drove shifted better than when I bought…. Drove to work the next day (45min drive) before I got to work yet again no pressure clutch on floor… found that the clutch slave cylinder was leaking replaced and bled system only for me to get almost to work today and again losing pressure… what are we doing wrong???

 

It sounds like you've still got air in the system, I'd try to bleed again.

Gravity bleeding worked well for me when I'm bleeding solo.
