I have Fluid Leaking In my Cab... Help!

So... today, i moved my floor mat a little bit and noticed some paint peeling.... I also had some fluid sitting on the floor pan... Well, turns out I have fluid coming in through the cab where the brake pedal goes through the firewall.

My brakes have always been a little messed up. I have to pump them once or twice so they work....

I thought this leak might be from my master cylinder or something, but here's the kicker... i still have just as much brake fluid in my reservoir as I did before.

What do you guys think? Is it the booster? Master cylinder? A seal that goes on the brake pedal where it goes through the firewall???

Help please!

Mine was the seal between th MC and the booster. When i removed the unit the booster was filled almost half way with fluid. I had to get a new MC and booster.

Could be a couple things. Brake master cylinder. You can take it off and take it apart fairly easily and clean it up. The seal can get a lot of build up especially on the bottom and start to leak through. Before you do that however is it for sure you brake master and not your clutch master cylinder which often looks like it is coming from the brake but is really coming down the clutch arm.

I believe it's the brake master. It's coming out of the brake arm through the firewall....
