Losing Brake fluid

[huck369]

I've been losing brake fluid on one of my SVX's, but can find no leaks anyone else have this issue, and find the culprit?
I've replaced the master cylinder, and searched for signs of leaks, but have found none...

How fast do you lose it? Can you park the car, pump the brakes and empty the reservoir?

If it's not around one of the wheels, my next guess would be the lines around the fuel tank

Sometimes I can drive for days without noticing it, and sometimes it goes pretty quick....never find any wet areas, and this is a southern car, with no rust, I' really don't expect it to be the lines over the tank, but even if it were, it should be leaving a puddle...

If you can't see any leaks Huck, it may be going through the booster vacuum hose to the manifold.

Thats what I was thinking, but he replaced his master cylinder.

Look under your car right where the lines go under the rear passenger seat to the underneath of the vehicle. There's a little "intersection" that the lines go through before going over the fuel tank. Mine was leaking but no fluid would show up anywhere, and that's where it was coming from.

I'll look there again, but had it up on the rack Monday night, and didn't notice leaks anywhere....

And Harvey, that should be ruled out, since I've replaced the Master cylinder....but I did pull off the vacuum line to double check, and it is dry inside..

I would try putting cardboard under each tire while it is parked and pump the brakes. I had a small leak in the rear and it would never leave a wet spot on the ground except until I used a cardboard. Try it.

It ended up being the left front rubber line to the caliper...wouldn't leak all the time, but would under the right conditions....Got a new one on the way...
