Would this work
I have an 02 zo6 and after hard driving my clutch pedal gets softer even after trying to remove old black fluid out of the reservoir. So what I was thinking of doing was using the mityvac vaccum pump to blead the system through the reservoir fluid inlet hole. If this would work great but if not where is the bleader valve at.
Thanks for any help.

to completely drain the system is a pain, you have to remove the big plate under the car that conatins the drive shaft (about 50 bolts)
On the other hand.... the black fluid is a result of the rubber cup thingy in the resesvior. I changed my fluid over and over (made no difference, just looked better) then I went my local GM parts counter and bought a new rubber deal for 12 bucks, no more black fluid. Whoever started the notion that the black fluid was a result of fluid that needed to be changed must sell fluid for a living.

Since new, I've kept the fluid in the clutch hydraullics fresh by frequent changes. it is never allowed to take on color.
If the clutch fluid is not changed, it become black, funky goo, and full of black bits. Owners who let the fluid get to that stage, usually experience clutch pedal woes, which, in turn, often are followed by tranny issues that flow from incomplete clutch disengagement.
My tranny remains perfect.
And for the record, I'm not in the fluild business.

Once the onset of "pedal woes" has occurred, changing the fluid may not correct the problem. But it's worth a try.
I suspect your clutch fluid is black...The Syringe for changing clutch fluid in the master cylinder ...I'd suggest changing the fluid every few days until it remains clear and then before and after each time to the track and again every time it start to look cloudy.
The reservoir holds about three ounces. The entire hydraullics holds less than 16 ounces. So it takes frequent changes initially to get rid of the crud and black bits.

Ranger has helped us out with great tips, techniques and awesome advise. His results are simply amazing too and I would jump off a cliff if he recomended it.
Seriously, I just changed out to motul 600 and my clutch feals beter than OEM ever did. The bad part is it is realy too smooth now and like a Lexus, kinda lost some fun factor I gues, but, great fluid. I bought a LAPD remote bleeder and it is at the shop but we did not get to it this round of mods. When the 390s go in, it will get done.
Hey for 12$ I am going to try that. I change my fluid before and aftr too (thanks Ranger) and I swear it helps. Mine likes a little slip and drive through it, and if I bog, the fluid gets realy hot, but it does not get soft at all now (we wrapped the lines when we bled the clutch, changed fluid... it's easier with the heads off
).Thanks!Dave

I have a spongy pedal when I heat things up and I have tried a few fluid changes with zero effect. Ive come to accept that that its the nature of the beast and will live with it until I invest in a better clutch.
Black (actually dark, like real weak coffee) fluid...
After the first change I discovered dark fluid again jsut a few weeks later, I went through the process again and the same thing happened.
I mentioned it to my mr goodwrench buddy and he laughed, asked me if I had changed the gasket. After spending 12.00 I have had clear fluid ever since....the pedal is still spongy but the fluid looks great!!!
I'm sure thier are better fluids availible but I have always used OEM liquids.
I dont take my Z to the track but I does see 6K on a regular basis, I love those "this is your speed" signs
