Brake fluid leak

Working on a 2000 GP GT thats been sitting for a while.
Got it started up and was going to move it and brakes felt squishy.
Sounded like air hissing out when i pushed brakes.
Topped off fluid and tried again.
Little bit of resistance and then nothing when i pushed pedal.
Fluid leaked from kind of under and behind the reservoir it seems like.
I cant see any fluid up top on the lines or master cylinder.
If i reach down under where the master cylinder attaches to the firewall i can feel the fluid.
Think its a master cylinder issue?
 


The booster attaches to the firewall, the master is then bolted to it. No fluid should come out of the master and into the booster, so you likely have a bad master at the rear seal.
 
Ahhh so thats what that round thing is!
Hahaha sorry complete newb here.
Treating this car as a project and opportunity to learn.
I'm pretty sure i checked and found no leakage dribbling down the front of the booster right under where the master attaches.
When i felt under on the bottom of the booster it was wet.
 
The lines do run under there, and straight back. Try to look under from the drivers side and see if the lines are wet starting at one main spot. You'll probably have to jakc it up to get a better look.
 
have some one pump the brakes while you look under the car on the drivers side, ( you should see a leak) the lines drop down from the master to under the car to the back of it, they rust all the time and blow out.
 


I would recommend looking things over and making a decision. Usually I'll do the line that's leaking and the one next to it that I end up hurting while doing the first line. Never do both at once..that's crazy talk :th_sick1:

If you think you'll end up doing a bunch, hit the parts store and ask for the bulk pack of the fittings you need. The fittings at the wheels to the rubber brake hoses are one size which also works on unions and then the ones going into the master or ABS are another different size. Also ...my suggestion is the NiCopp line. It's super easy to bend, will never rust and makes install about 10 times easier/faster for a first timer. Also a nice double flare tool, got mine from Sears and it's been great for probably 50-75 flares/repairs so far. I'd tell you about a power bleeder...but I'd rather everyone was jealous.
