This thread is to show what I did for the Rear Disc Brakes on my 1984 Monte SS.
Front Brakes are C5Z06 setup on Blazer Spindles

I used the Rear Disc Brakes from a 1995 LT1 Camaro Z28. I wanted them because they came from an old car of mine and they clear 15" Drag Wheels with minimal clearancing needed. The information here will be pretty much the same if you use the LS Fbody Rear Disc Brakes, or Corvette Rear Disc Brakes.
Pic of them on my SS how it sits.
I ordered a QP 9" Housing that had Fbody End Caps on them so everything bolted right up.
I have the Disc/Disc Combination Valve installed on my SS.
However you get them bolted up the process is the same:
Install Backing Plates
Install Axles
Bolt up Calipers, check clearance with Rotors
Hook up Brake Lines and Ebrake Cables
Brake Lines are pretty straight forward, hook them up and properly bleed the system.
The E-Brake/Parking Brake hook the stock Fbody/Corvette cables to the levers on the Calipers and integrate them into the setup on the Gbody however is best.
Here are the cables hooked to the levers on the Calipers and locked into the small Brackets.
I mounted the Bracket from the Fbody here above the muffler that takes these 2 cables and hooks them to a single cable going to the front of the car.
Now here's the technical..
For the Gbody guys running 4th Gen Fbody Rear Disc Brakes or Corvette Rear Disc Brakes and need the E-brake/parking brake to work I solved that problem.
The Gbody uses the floor pedal, the Fbody & Corvette uses the hand lever, both have different fulcrum lengths of pull. The foot pedal travels roughly twice as far as the cable pull on the Fbody & Corvette Rear Calipers. This makes a 2:1 ratio.
I fabricated and installed a small lever on the frame to give the setup that 2:1 reduction from the foot pedal to the pull on the Calipers. A turnbuckle is installed on the Caliper side to make fine adjustments on the setup. It works perfectly. The cables have no slack or tension when the E-brake/parking brake is not in use, and when the pedal is almost fully depressed the brake is fully set with the car not moving on a 15* incline.
Here is the lever installed on the frame with the cables hooked up. You can see where I used Ubolts to loop the cable and hold it in place, been working fine. Just make sure there are no sharp edges.
This is a close up of the lever with the brake engaged, just a simple 2:1 reduction mounting point for both cables and bolted to the frame rail.
The two above pics are older pics, since then the Cross Member had been modified and is sitting ontop of the Frame Rail like it should be and the cables clear under it fine.
Here is the cable going from the lever to the junction where it splits into both sides. The turnbuckle is for fine adjustments.
This has been working in my SS with zero issue since this thread was posted in June 2016. The 2:1 Ratio is key with the Fbody & Corvette Rear Disc Brakes. Blazer Rear Disc using the Foot Pedal you most likely wouldn't need to do that.
All 4 corners work excellent with the Disc/Disc Combination Valve.
These above are older pictures, since I put my front C5Z06 Calipers on now, they all are red.

C5 Z06 FRONT BRAKE SWAP
Today I installed C5 Z06 front brakes on my SS. I had been piecing this together over the last couple weeks. Parts breakdown: ZQ8 Spindle Adapter Brackets: $125 (eBay, link constantly changes, have to search ZQ8 C5 Brake Adapters) C5 Z06 Calipers, Brackets, Lines: $180 (VetteVillians) Z06...
