Rear brake swap problem

[Dream240]

Okay, I finally got the rear brake swap done. I swapped in a 17/16" MC and used the existing rear knuckles. Here's my problem, the right rear wheel grinds when I'm driving. It sounds like the drum shoes are rubbing on the inside of the rotor hub. I took the wheel back off and adjusted the shoes to be fully "in" and they still make that noise. It couldn't be the actual wheel hub rubbing on the inside of the rotor hub right? The other thing I suspected was my pads but I'm pretty sure it's not them cause it will still make the sound when I'm braking.

Here's the setup I have: Z32 rear calipers (rebuilt), CD/Slotted rotors (ebay), Axxis ultimate pads, Z32 e-brake setup with good shoe life.

Oh I forgot to mention, I couldn't get the ebrake set up yet, ran out of time yesterday, so the cable are jsut tied up under my car. So the cable can't be pulling the shoes too tight cause they're not even hooked up right now.

Any thoughts??? HELP...?

Okay, new problem.

Now I have a loud whine in my FRONT driver's side brakes!! I was thinking that I crossed the brake lines from a front line to the back, but I double checked them last night and they're all exactly where they're supposed to be. Also I noticed that the Master Cylinder is leaking from the lid!! I screwed it nice and tight but I can see fluid dribbling down the side. I'm wondering if maybe the rubber gasket on the inside of the lid is just bad? Hmmm....anyone have any info??

Oh yeah it's a used 17/16" MC off a 300zx.

Help??
