Horrible hard clutch pedal after hydraulic install
YES
Not long ago you admonished "us" to STFU and not answer a question to which we do not know the answer
But this is a question that can NOT be answered with the information you have given
Did it ever work right?
Is this something new you have just installed?
What sort of "setup" is it, I.E. is this something you bought "that is designed" for this type of setup, or is it a junkyard Toy, Datsun, etc?
Hydraulic clutches are "simple"
You must take into account:
1 the leverage of the clutch fork, which is difficult or impossible to change
2 the leverage of the pedal, might also be difficult or impossible to change
3 the diameter of the slave cylinder, larger bore = less travel, less effort
4 the diameter of the master, smaller bore = less travel, less effort
6 the pressure plate: most diaphragm clutches need less effort, most B&B need more, some need a LOT of effort
7 I suppose it's possible that you have something in the tube/ hose, probably doubtful, but aren't you "over there?" Have you used components of the marvelous "Girling" system, which (at least used to) require special brake fluid, otherwise the brake cups will expand and self destruct
8 as mentioned, something bent/ binding/ out of line
