Master Cylinder leaking?

[White70C20]

Good idea Wrenchbender!

I have checked the master cylinder. It's brand new and not warped. The gasket in the cover is new. It's not leaking from between the master cylinder and the booster.

I was talking to another car guy at the college I'm at and he was suggesting adjusting the rear brakes too. He said since I replaced the front shoes, they aren't having to travel as far as they used to which makes sense. The rear shoes are having to travel farther and they can't do it unless I adjust it.

If that doesn't fix it, I'll have to bleed the brakes. The guy I know has a one-man power brake bleeder made from an old car oil pump. It should work pretty well, but I hope adjusting the rear brakes will take care of it.
