Default Clutch Hydraulic Leak. Please Help me find it????

I replaced the adjustable master and still had the same problem. I switched from the Mcleod to the Ram adjustable. I then replaced my 02 slave with a new 02. The first 02 slave I had was put in with my new spec stage 3 clutch about 10 to 15,000 miles ago. The slave was leaking. After I replaced the slave again this weekend I still have the exact same problem. I can shift smoothly with no problems until I stomp on it. Then the clutch moves a couple inches closer to the floor and I can not get into any gear. I have to pump it about 10 times and it will finally return to normal. Right after that sometimes the cutch will disengage and the motor will rev up and then the clutch will engage and I never pushed the clutch in. I am guessing that is from the brake fluid leaking on the pressure plate. I am 100% sure the system is bled correctly. No air in the line. I have a pressure bleeder that I have hooked up to the top of the master cylinder reservoir. I drove the car with it hooked up and I could shift WOT. After a few WOT runs the problem would reappear but not as frequent as when it was not hooked up. Normally as soon as I stomp on it I have the problem. Could there be a leak somewhere besides the slave? Maybe where the steele braided line from the master plugs into the tranny(slave)? Has anyone else had a problem like this? I looked at the pressure plate when the slave was being installed and the fingers were fine. Nothing was bent. The paint on the pressure plate had been eaten off by the brake fluid leaking.

Also there is a shim that you can use on the slave. I was told that normally it was never used. Should I have used it?

I bled the hydraulics the normal way pumping the pedal 7 times and holding it down. Then cracked the valve to let the air out until fluid came out and closed it. Then filled the reservoir with fluid. Repeated that like 30 times. Then I used a pressure bleeder at the top of the master reservoir. I have been bleeding like this every weekend for 4 weeks. Still have the exact same problem. Me and my brother bled our camaro's at the same time the first time we tried. His camaro is perfect and I am still having problems. I think I have a leak in the hydraulics somewhere. I just can't find it. Any suggestions?
Thanks

If your losing fluid then the only thing to do is trace the line from the reservoir to the slave and find the leak. Check around the master really good too, I've heard of them leaking there. I know it sucks and it's a PITA but that's about the only option you have.

I know I posted this on another thread, but I just did my clutch this weekend and attempted the drill out mod...I guess I let it get too hot while drilling and it melted the lining inside. From the out side it looked ok but when i put pressure on it it went everywhere. However this dosnt explain the brake fluid getting on your pressure plate. I used the shim when i put the slave in, it just helps by moving the slave/throwout bearing closer to the pressure plate fingers there fore making it disengage more. I dont think that you have a problem bleeding it because I only pumped mine like 20 times and bled it off and it works just fine. I dont understand why you still have the leak after changing the slave again....thats the only source of fluid going in there....even the line dosnt actually go into the bell housing, so if it was leaking from there it would just drip on the ground. Let us know when you find out whats wrong. Good luck.

I will do what I have to do to fix it at this point. I have a feeling my only option is to completely disassemble the tranny and clutch and reassemble. Of course I don't know how to do this nor do I have the tools. I am guessing it is going to be expensive. This sucks having all this power and having to drive like a grandma.

I hooked up the pressure bleeder again and had somebody pump the pedal to see if I could find the leak. No leak in the line anywhere. I traced the line and there is no fluid leaking anywhere. I did the drill mod and I was thinking the same thing, if it is leaking from the line I would see it dripping on the ground. TrackBurger I saw your other post and was hoping that was my problem but it is not. It has never leaked on the ground where I could see it. I took the car out with the pressure bleeder on and still no trace of a leak anywhere in the engine bay or anywhere that I can see and feel. I am not sure if the new slave is leaking this time but I still have the same problem, so I am assuming there is still a leak. Who knows this is ridiculous.

The tech at spec said the clutch disk and/or pressure plate might be deformed from the brake fluid leaking. He said that they might have absorbed the brake fluid after leaking for so long and under WOT or constant beating became deformed. But then why does the peddle still fill spongy and act like it did when it was not bed properly?

I really appreciate the help. Do you guys know if I would be able to see it leaking out on the ground, if it is still leaking inside the tranny(slave)? I have never seen a leak on the ground before.

What do you guys think about replacing the clutch disk and pressure plate next?

Mine is a 00, but I'm sure the bellhousing is the same as yours, anyway...If the slave was leaking yes is would still drip on the ground. Right where the belhousing bolts up to the block, at the 6 O'clock position on the bottom there is a little rectangular vent hole. If the slave was leaking it would come out of this hole and onto the ground. When i bled mine some fluid ran down the inside and came out that hole.

I think I may know what your problem is. You posted that you didnt use the shim that came with the slave. I toutched on it briefly in my other post but I think you NEED to put this in.There was no shim on the stock slave due to the design of the clutch...The spec clutch has different tolerances and therefore the slave needs to be moved or "shimmed" forward so that it will operate correctly. I think this may sole your problem. <img border="0" alt="[burn out]" title="" src="graemlins/gr_burnout.gif" />

Son of Biatch. If that is the case then I wasted a shitload of time. <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" /> I hope you are right. I will try that this weekend. Thanks

Yeah, I hope that works for you. I know how disapointing it can be to put a lot of work, time. and money into something and have it not work. I really think this will solve your problem, but dont hate me if it dosent. I keep reading the posts over and over again and cant seem to think of anything else it could be. Good luck and keep us informed. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

TrackBurger: I had a couple friends drive my car and they all said the same thing. The clutch is not disengaging enough. It is sticking at WOT. I like my peddle about 2 inches lower than my brake peddle. I can shift better (smoother and faster) with it like that. I don't want to move the peddle out anymore so I need the shim. I wish I would have put the shim in last weekend when I put the new slave in. At least guy who did the install for me is only going to charge $75 this time.

My brother has the same setup but he likes his peddle even with the brake peddle and of course he does not have the same problem. Now that the slave is fixed the peddle has the same feel except that the peddle gets harder to push in at WOT becasue it not disengaging enough.

Well at least I found the problem. Thanks
