I had to replace my slave cylinder. Was out of warranty so I did it myself. Cost me 170 for the part. Not a hard job. The best way to see if it's leaking is ofcourse look into the resevoir like you guys have already disgussed, but it's also really easy to remobe the 2 bolt holding it onto the tranny. When you pull it out you'll see the boot is all soaked and brake fluid will be dripping out of it. It's a plastic piece of crap. Bound to fail again. Also, the AC water drain drips water right onto the slave cyl. when the AC is on or the knob is in the defog position. This can't really help matters, although I don't think it's causing them to fail. Just a cheap part. Mine was also the 3rd on that I've heard of locally to me.

To start off I don't claim to be a machenic by no means. but I grew up working on older cars and trucks with my dad (back before computers were under the hood) so I do like getting my hands dirty when I can!
So my girlfriend and I went out to eat saturday evening and came home with no problems. Sunday morning got in the jeep pushed in the clutch to crank the jeep and it went to the floorboard! I could'nt believe it !! did I burn my clutch up?? You usually get some slipping or somthing before it burns out. Unfortunatly I didnt have time sunday to deal with it. So Im in missury all day sunday thinking I somehow burned my clutch up. I then remembered I had to replace a slave cylinder on my older jeep before and that had to be it. Ok I can deal with that right atleast its not a clutch, but I hear its a bitty to get out of the JK's Maybe it will be a line that is leaking or somithing of that nature. So I get out and get under my jeep no fluid on the ground no leaks anywhere so I was kinda scratching my head.
I opened up the brake fluid reservoir and where the line from the slave cylinder goes into it, it looked like there was a seperate reservior inside that had no fluid in it. The smaller resvr had a small square hole at the top of the resvr that looks like it will allow brake fluid overfill in it. [
]So i cut a straw and stuck it in the square hole and filled it to a safe level and closed it and started pushing in the clutch for about 10 minutes , by joe the pressure was coming back. so after getting the air out of the line i went back and filled it up some more and wha la it seems to be good as knew I hope!!
I have to admit I felt like a complete idiot realizing that this could have been a very expensive oversight not only on my part, but the dealerships part cause I have had my jeep up at the dealership about 6 times for oil changes since they send me the discount coupons and I know they check all the fluid levels. I was wondering wouldnt they know to check this? in all honesty evan if you check the brake fluid you have to look in this small sqaure opening to check the levels for the slave clyinder , to me this looks like poor designing by jeep.
And throughout this there have been no check engine lights of any sort come on.
Sorry for the very long story, but unless anyone knows of a better way of doing this all you munual transmissions out there ! open up your brake fluid reservior and make sure your fluids levels are good.
I took some pics to explain what I'm talking about , I will try to post asap

Well, tonight I was driving home and coming up to a stop light. I start to depress the clutch and "pop" ...the clutch goes straight to the floor without resistance. I was unable to put it back in gear while the Jeep was on. I had to call the tow truck and the dealership now has it until I talk with them tomorrow. I am scratching my head as we speak as to what just happened. Is this the same problem or something else???
