My 85 stang gt four eye has a booster question. It hisses untill i step on it to break... also my car takes a long time st start. Will the leaking booster cause this? Its a carb car not stock. Its a four lug and i dont plan on doin 5 lug. Or rear discs so no need to upgrade.o

Vacuum leaks can do all kinds of weird things.
Car looks pretty nice, though. I love four eyes.
