Mighty-Vac Bleeding Clutch - How To?
I bought a Mighty-Vac hoping I could use it to more easily change the fluid in my clutch system. I have a remote bleeder installed but when I attach the MV, crack the bleeder and apply vacuum I do not get any fluid. Should I be able to suck the fluid from the master cylinder by doing this?
Those of you with Might-Vacs what method do you use when bleeding the clutch system?
Thanks

I got it. Had a leak at the bleeder fitting so it was sucking air.
Unbelievable how much black crud gets built up in the fluid. I use to do the ranger method every 6 months now this MV makes it a breeze.

Bleeding a Clutch Via an Installed Remote Bleeder

A remote bleeder and Mity-Vac are absolutely essential to making the clutch bleeding procedure a one-man operation.
Connect a Mity-Vac to the outlet on the remote bleeder. To ensure a tight seal, apply a little “sil-glide” to the threads on the bleeder
Next, start by draining the reservoir with a syringe. Refill with clean fluid.
Then proceed to pull a vacuum & pull the fluid in normal flow direction w/ the Mity-Vac brake fluid bleeding attachment.
Keep doing it till the fluid comes out clean. Make sure you keep the reservoir at the proper level throughout.
wrencher states: I usually keep an eye on the fluid color & flush by the look of it.
I drag race my car a lot. I flush before and after every track visit.
If I don’t, the pedal changes & I know it's flush time.
I do a fluid change & all is well again.
By following this routine, I’ve kept my master cylinder working correctly for 3-4 years now while doing a lot of racing.
Thanks to wrencher for the info.

Your hydraulics will be damaged by any silicone fluid, because it can't deal with moisture that inevitably enter the system. So you want to stay with DOT4, which is the spec brake fluid for all M.Y. Corvettes with a hydraulic clutch. Some fluids are marketed as "super" DOT4, but the differences are generally "marketing."
