clutch loses pressure...97 tj 4.0 5 spd

so my clutch lost all pressure yesterday. i got it back to camp and added fluid to it pumped it up and the clutch came back (temporarily) now i have to pump the clutch if the jeep sits for any amount of time (im talking minutes).

The hydraulic clutch system has sprung a leak. Luckily, it can be replaced without much effort or trouble... hard to say if the master cylinder or the slave cylinder is leaking, you're going to have to look.

funny thing is its not losing fluid (or it doesnt seem to be). it was never empty. it didnt take much when i topped it off and its not low now. i dont see any way to bleed the system either?

Oh misread what you said but it's clear that air is getting into your hydraulic system. It has a leak somewhere.

Some have been able to bleed it, somehow, but the factory did not include a bleed screw or intend for it to be bled. The factory intended on the entire master/slave system to be replaced as a pre-filled/pre-bled unit. I've never personally tried to bleed one, I removed my previous manual transmission before it ever had that type of problem.

i may just replace the master cylinder to see if that fixes it. its kind of a silly system that cant be bled. i cant see a leak in it anywhere. its not losing fluid that i can tell.

Master cylinders for brakes can get internal leaks and fail, I don't see why the clutch MC couldn't do the same thing....

doesnt really make sense. the master and slave were both replaced when the frame swap was done a couple months ago.

That doesn't preclude them from being bad. "new doesn't equal "good".
