i have just bled my hydro clutch in my car.
i still only have 3 inches of pedal travel till downwards its fully disengaged, which is harsh, how do i make it so i have more space till it starts to move the clutch cylinder

Try playing with the adjusting nut on the MC. It will be up under the dash on the pushrod that's hooked up to the clutch pedal.
Just loosen off the locknut and adjust accordingly. It might be a difficult job, just because actually getting to it isn't easy!

you shouldnt ever have to adjust anything with a hydraulic setup, unless someone has messed around with the adjustment at the m/c but you shouldnt need to really.

are you sure there isnt adjustment? usually the rod connecting the pedal to the m/c is adjustable. i wouldnt think the m/c leaking would be related to the clutch be adjusted up too much.

there is no adjustment, the rod is only 3 inches long, theres the clevis joint on one end, and then the rod goes into the boot in the other end

I had a leaking MC once which after rebuilding had a completely different pedal feel. Though I can't recall if it effected the free play a great deal. A rebuild kit should cost under $20, and maybe an hour or two at the most to do, if you don't want to get a whole new MC
Brake fluid's nasty shit to have leaking anyway, so at least there's no loss in fixing the leak if it doesn't do much else

i got a rebuild kit for about 20 for a ke30 rolla, it lasted a while then started leaking again... then i thought id have to fork out a lot for a new master cylinder but it turned out to be only about $40, should have got it in the first place!
bit of tech for future use: (any input welcome)
with the clutch pedal, the pedal needs to have a certain amount of travel to empty the master cylinder to the slave, the pedal can be set at a different start point by adjusting the travel of the pedal at its start of the stroke(adjusting nut up top) and the end of the stroke (master cylinder rod just touching)
the master cylinder needs to fully empty to the slave to disengage the clutch properley so when the pedal is setup, it has to be checked that:
the master cylinder is not being pushed at the start
the master cylinder fully empties when at the end of the stroke
so obviously if the setup is wrong then the master will be pushing at the start (leading to the clutch being disengaged at the start) or will not be empty when at the end (not disengaging at the end)
say you have from 0 to 300mm of pedal travel and your master needs 200mm of travel. you can have that 200mm of travel anywhere in the 0 to 300mm range:
eg
0 start to 200 end = 200
50 start to 250 end = 200
100 start to 300 end = 200
but you cant have it out of that range:
eg
a 200 start would be a 400 end to get 200 travel,
but the pedal stops at 300 so you only have = 100 of travel which isnt enough, the pedal would be pushed against the floor.
and the clutch would only be half disengaged!
a 100 end would be a -100 start but pedal starts at 0, so you would have only = 100 of travel, the clutch would be halfway disengaged at the start and the master would have constant pressure against the seals, not good. it will still disengage fully with the stroke but it would be half disangaged from the start all the time!
