So I bought a 67-76 Corvette master cylinder with 1" bore. While bench bleeding, I'm noticing the rear side of the MC doesn't start pushing fluid right away. The front pushes fluid immediately.. On the rears, I don't start getting fluid movement until about half way along the piston stroke. I then put my old MC on and it's doing the same thing. WTF? Don't know why I didn't notice it before, but I think that explains my late pedal? If I don't get fluid going until mid-stroke on the piston, that would explain why the pedal seems to always engage late. The front brakes have been hooked up to the larger rear reservoir (it's one of those cast iron MC's with the large reservoir in the rear and small one up front). SHouldn't both ports push fluid at the same time upon pressing on the piston?
