I have changed my clutch master cylinder quite a few times already. And the problem still persist. I'd notice every so often, 2-4 months my clutch reservoir would be empty. Theres no leaks around that area or where the clutch slave cylinder is at. Just recently the clutch pedal would just stick to the floor. Checked my reservoir and its empty. put some more fluid and its all good again. However today I changed out the old slave cylinder and now the pedal is worse. It has no pressure, I bleed the lines and still no pressure. Then I changed out the master cylinder. Nothing. Why is there no pressure?

 

Because you're losing fluid or you aren't really bleeding it properly?

If you truly are bleeding it correctly you can try the following: Fill the reservoir and bleed it as good as you can. Find two friends and have one pump the clutch while the other keeps the reservoir filled. You need to follow all of the hard lines though the engine bay to see where it's leaking.

 

No doubt. I'll definitely check that area out again. Finally got pressure back up. The new slave cylinder bleeder valve was leaking. Grabbed the old one and put that in place. And DAMN.... Took a while to bleed all that air out also. Gonna check for leaks again tomorrow. Thanks guys.

 

I'm losing fluid as well and can't seem to find a leak anywheres. Any ideas? Its a 93 Hatch with a JDM b18c (gsr) tranny.

 

Check the bleeder valve. Mine was new but it was bad, didnt seal properly. Have someone pump the clutch while you watch it to see any small leaks. Pump and hold it down, thats how i found the small leak, air was moving thru it. My clucth fluid is super clear still, been about a couple months since i posted this thread.

 

Thanks for the advice man
