Does anyone know what would cause brake fluid to leak from the caps. The master cylinder is new(not reman) the brakes were just bled. I have steel braided lines, and it is NOT over filled. So somehow the fluid is getting through the little slit in the rubber seal and leaking out of the caps. Now at first I blamed it on the wicked hill I live on since the angle of the incline is so steep I thought maybe it was causing it to fill one side too much and leak that way, but it will eventually drain the whole resevoir so I no longer think that's the culprit. Any ideas? Perhaps I got a junk MC? Whatcha got?
