Hydraulic Clutch issues

[driftingmustang]

OKay, so lately my clutch has been having an issue were it has a dead zone that progressively gets worse the less I drive the car. (no ressistance, engages at the bottom). So I bleed the lines refilled it and bleed it multiple times because the fluid was black so a basicly tried cleaning the system out figuring ut was overdue for a change and that was the source of my problem or there was air in the lines. did this and for about a day it was great, felt like brand new.

Now its doing it again except driving around or pumping the clutch doesnt help, it instead makes it worse. I cant find a leak and my reservoir is full, the slave and master were changed less than a year ago. What is wrong?

(you may call me a retard if you wish as long as your informative, lol)
