Okay a month ago my clutch hydraulics went out on me.. I rebuilt the master cylinder, removed that stupid section between the master and slave, and bled it good. Clutch felt better than ever before.

Well, Saturday morning I jumped in my car after letting it sit in the cold all night, pressed in the clutch and the pedal felt HORRIBLY soft. I could feel the engagement point was nearly to the floor. However the car drove fine up to the gas station, where I bought some brake fluid and opened up the master cylinder, to see the resevoir nearly empty. There was a bit of fluid in the bottom. I filled it up, pumped the clutch a bunch and now the pedal feels fine, almost back to normal. Still a little squishy but I'm guessing it just needs to be bled again.

The system was FINE the night before! Not a problem at all!

The fluid is now a bit cloudy. I'm guessing it just brought some loose particles up into the resevoir, no big deal.

It's now Monday, the system still feels okay, but I can tell it needs to be bled I'll probably do that tomorrow after work.

Any idea why I may have suddenly lost a bunch of clutch fluid? And what can I do to keep it from happening again?

I guess to be sure I should just say screw it and rebuild the slave cylinder huh. That should be much easier than the master cylinder. And I would feel much better.

Did you fill the clutch slave with brake fluid when you finished?

What section did you remove from the master to the slave.... was it like a box?

Did you bleed the lines untill all the air bubbles were out and you were spraying solide brake fluid?

I need more information....

Yeah I removed the clutch dampener. A little system designed to reduce excessive shock to the clutch, but in all actuality is only there to trap air in the system.

I bled the system perfectly. No bubbles, didn't take long after removing the dampener.

You mean did I fill the master cylinder after finishing? Yes.

that clutch tube holding system serves a purpose more than to trap air and to put less shock on the clutch system... i dont think it was a good idea to remove it... but other than that i dont see the prob except for you slave,,,

nope. i've read of many people bypassing the block and not having any problems. unless the block itself is leaking, it's the least of your problems.

of course, check for obvious leaks, but i bet it's your slave cylinder.the best way to check it is to get someone to pump the clutch pedal while you look underneath the car. if you don't see any leaks, pull the rubber boot off the cylinder itself. fluid should come out.

Alright, thanks. I tried looking under the car while I pump the clutch and I don't see any fluid leaking. But I'd imagine the problem is there..

BTW today is Tuesday, the clutch has been fine since I filled it back up Saturday morning.... :confused:

hey ive had major probs with my clutch... 1 night i came home with the clutch fine.. in the morning wit 5 mins left to get to work.. the engagement point was at the floor.. i mean baaaad.. then wen i got to the intersection.. i couldnt shift.. so pushed it home like 200 feet... first... bled the WHOLE system.. no good... then.. replaced slave cylinder... no good... then replaced master cylinder..no good.. then NEW clutch assembly.. GOOD...

but then.. 5 days ago.. i got in the car and the clutch was slipping like a mother *****ER if i hit gas more than an 1/2 and inch it would slip and the engagement point was at the pedals full height..

so.. brought it to a transmission place that did my clutch.. (free) and he did an adjustment .. now it grabs off the floor and he says im gonna need to come back in a few days for another adjustment.. WTF!?!@??! i dont get y i have to come back.. and i hate this ****.. he said like 2 days ago i could pick it up.. i did.. and it wouldnt shift for nothing.. now im gonna go back tonight to see.. any thoughts??

edit: my mechanic ALSO told me to come back too!!

i had this problem after replacing my slave cyllander. turns out, when i bled the system the master piston thing travelled a little further and i took a piece out of the seal so it was bleeding into itself. After i replaced the master, it was pretty far out of adjustment, and the engagement was right on the floor and the clutch wouldnt return to full height. I took the master back out (without disconnecting the lines) put my old one up to it, and adjusted the little fork and rod thing so it was just about the same (i put it in a little more so it would release a little more towards the floor) and now it works great.
