97 with 200K bleeding brake fluid some where
 

Today I pulled the master because I had already checked each wheel to see if I had a leak, nothing.

I figured it must be leaking from the back of the master, it was nice and dry.

I've looked at the ABS unit and don't see anything, same with the lines leading to the rear. I haven't raised it up just laying on the driveway with a flashlight.

It's not rocket science, it's just a leak but I can't find it yet. I haven't put it up in the air and done a really good under car inspection but I have gone through two masters of fluid and I'm not seeing anything. It will bleed down the master overnight.

Is there something I'm missing where it could be going ??
Anyone have a leak they couldn't find for a while but finally did in an unusual spot ??
