Front Brake Bleeding

I'll tell ya what's going on.
There is something up with the banjo bolt at the master cylinder. I did some troubleshooting by disconnecting at the switch. No fluid.
Then I got the genius idea to force fluid into the little hole at the bottom of the reservoir using a air needle with a hose and syringe attached to it.
Suddenly the brake lever is as hard a rock. Pressure! Ok, lets see where fluid is. Cracked the line at the switch. No fluid. Hmm....this is odd.
Cracked the banjo bolt at the mastercylinder. Holy hell fluid everywhere, and now no pressure at the lever. So...no fluid is getting past the banjo bolt. That isn't right.
Take banjo bolt that has one exit hole and drill thru it to create a second exit hole. Re-pressurize master cylinder. Still no fluid going anywhere. Reposition brake line/banjo joint. Hit brake lever and sudden fluid is passing! Hurray!
Ok, so now the brake works, but its dragging like a confused teenager. I'm thinking something is up with that master cylinder banjo bolt that is keeping fluid from flowing nicely. Anyone have a picture of one on a brake that works well?

Spicey!
I guess it's all a matter of the banjo bolts being lined up and having an unclogged brake line.
Perhaps you need to rebuild your MC?

that's actually why I was bleeding the brakes, I just rebuilt my master cylinder.
It could be a non-oem line that just doesn't work well with the stock banjo or yes, I clogged line. Now the thing is, how do I go about solving the problem of brake drag if it is related to fluid not flowing well?
I'm hoping the caliper just need greased up...I mean...they haven't done anything in oh...a few years.
