Invisible brake leak
Hi all, I have a very annoying brake leak which I cannot find no matter what I do. The car is an 86 vert and I've replaced pretty much everything brake related except the lines. There are shiny new cross drilled and slotted rotors on there with hawk low dust pads. The car stops great but there is a leak somewhere.
Every few days, I find that I'm missing brake fluid. I even came close to running on an empty reservoir once. I looked EVERYWHERE and even wrapped the ABS unit with towels hoping to find them wet but nothing.
How do I chase this leak and find it? I already tried leaving clean white mats under the car and it doesn't leak anything at all. WTF? Where could it be leaking that I can't see it? Any tricks like with pressure or anything?
Thanks
Lee

The mastercylinder can and has before leaked into the vaccum booster and into the intake as he said in the above post. Break the black rubber line loose and see if you have any oilly film if it does, theres your problem and just yesterday we had a post going as to replacement of the M/C cost and where to buy.Good Luck

I had a similar problem last year. After leaking enough, I finally figured out it was a leaking brake bleeder. Installed a new set of "Speed Bleeders" and used teflon tape and the leak was gone.

Thanks for the suggestions guys. All bleeders looked dry and I checked those first. I never thought the M/C can leak INTO the booster. I'll take that apart this weekend and see wadafuxup. Thanks again -Lee
