losing brake fluid
 

since i removed my master cylinder ive been losing brake fluid, the brakes are way too sensitive, it locked up on me at least 3 times, and the pedal is spongy, it goes to the floor every time and i can hear a hissing noise like air is escaping from the booster. will this all go away after bleeding it or is it more serious like a faulty master cylinder or worn seals? it doesnt feel as safe as it used to be, btw i dont have abs

Do NOT pass go. Never touch your brakes if you don't know how to repair them properly.

Go directly to a qualified shop and have them repaired.

STOP ! Playing with your (and others on the road) life.

i realize that, but any suggestions on what it is exactly, i feel that you are underestimating my knowlege and expertise becasuse of my age, im only 17 and everything i can do myself ill do it something i cant do ill have a mechanic do, im tight on budget and therefore my labor is cheaper.

It sounds like a bad master cylinder. The seals are probably bad.

If you need one though, I have one from my 87 Turbo that looks line new(with no rust) and works great.
