1992 Ford Aerostar LEAK

Most likely your gonna need a new wheel cylinder wich dont cost to much bout 11 to 14 bucks. Or do what I do when those things leak most often is just the rubber bushings or rubbergaskets that go on the ends of cylinder its takes 2 of them, I just change those without even removing the breaks but thats me.U should just buy the whole thing new its not expensive. Go to kragen. Com and check it out and prices. Btw also check behind break chamber the oil line and check for any leaks just incase but I dought that. Just gonna be wheel cylinder mostly always is. Good luck
