hydraulic clutch pressure

[earthman]

I shortened a clutch pedal for clearance and it did not make the pedal hard to push. But the Ford master and slave cylinders were cheap plastic, broke and leaking. 3/4" and 3/4" i think. Replaced with Speedway supplied 7/8" slave and 13/16" master. Don't remember now how i came up with these sizes but the clutch
is too stiff to use comfortably in traffic now. Does anyone know how the ratio between master and slave affects pressure?
Should i just go back to evenly matched cylinders? Don't want to replace both if i can help it.Thanks

I'll bet you don't have to push the pedal very far to disengage the clutch. If that is true, can you shorten the distance from the pedal pivot point to the master cylinder push rod?

No, it's very close now. Thanks Bob.

When the master cylinder and slave cylinder were the same size it worked ok! Probably have to change one or the other to get back to what you had before. If the master cylinder is smaller than the slave it will produce more pressure but will require longer pedal movement to push the slave, sorta like a hydraulic jack?..[P

The jack comparison makes me think i should go with a smaller master. Thanks Fuzz.
