I recently replaced my master cylinder with a rebuilt one from autozone and now I have a leak coming from somewhere. I tightened the line fittings as much as I dare to but there is still fluid dripping from somewhere. It is a significant leak, after about a week and a half the front reservoir was empty. Judging by where the fluid is on the outside of the MC, I am guessing it is coming out of the top somehow. But I cant figure out why. Anyone have any ideas?
