ok fellas, here's an update.

So I sent my calipers to Mr. Rusty, with new rebuild kits from Z1. Mr. Rusty did a phenomenal job rebuilding the calipers. At his recommendation, I replaced all the bleeder screws, and added all new hardware kits for each caliper. After a few days, I received the rebuilt calipers, I cleaned up the brake pads and reinstalled everything.. while waiting for calipers, I had ordered then installed new stainless steel brake lines from Z1. I then installed the calipers back on the Z.

I know this is anal retentive but I wrapped (the black plastic tubing thats cut down the middle) the brake lines just for an extra layer of protection.

Today, I rechecked the stop lamp fuse (drivers footwell) and the ABS actuator fuse (near the battery) both were good to go. I also checked the brake switch sensor located on the brake pedal, comparing its position (counting the threads protruding out the bottom) to Mr. Madwi's Z.. to my amazement, his sensor was approximately 2.5 threads out the bottom which is normal, compared to mine, I had at least 10 to 13 threads showing below the base that holds the sensor in place.

which means, my sensor was sitting wayyyy below where it should have been.

I ended up pulling the brake switch sensor out, disconnecting it, then figuring out how it actually locks into place.. long story short, its in the exact same position as like Mr. Madwi's Z.

So tomorrow, I'll finally get the brakes bled and see where we stand. Fellas, thank you so much for your help and insight. I honestly owe you all a cold beer down at ZDAYZ.

I got the brakes bled today, said a prayer, turned the car on.. the brake pedal felt smooth and even.. and NO indicator lights!!! We're gonna keep the car up on jackstands and see where we are a week from now..

Well boyZ and girlZ, after a prayer and a phenomenal bleed of my brake system, as of today, my Z is finally up and running!! the brake pedal feels smooth and consistent, no leaks..brand new brake fluid.. no indicator lights, no squeaks or squeals.. I still have a funky smell near the passenger side intake manifold, so I'll be keeping an eye on that, other than that.. I'm blessed.
