Well i don't want one. I'm just asking in case there is a difference that shows itself later on. Like brake pad wear or something like that. Guess I'm just curious at this point

 

In my opinion, for whatever that's worth, You don't need one. It's my understand that there really aren't any difference in master cylinder, proportioning valve, or much of anything else between drum or disc rear brakes. Fair few folks have swapped rear ends for the discs, and that was the extent of the mods, and the brakes worked fine.

Your rear pads should last right around twice as long as the fronts..... Depending on how much you tow/haul. (more weight will allow the rears to do more work.)

 

I did the Dana 60 drum brake rear to disc brake rear swap a while ago and had no issues with the swap other than changing the ABS speed sensor on the newer disc brake rear to the 1996 model sensor since it had a different electrical connector than the newer disc brake rear's sensor had. I used the same master cylinder and see no need for any additional proportioning valve. I had changed all of the hard brake lines to stainless steel and the flexible lines to braided versions. The truck definitely brakes better with the new rear disc brakes.

 

Yep I am at the same point as you. Copper hard lines, speed sensor. All that stuff. Have you done anything with the emergency brake though? Haven't figured that out yet and need it before I get an inspection next year

 

Yes, my parking brake setup is connected and working. You will need the rear disc brake style parking brake cables that go to each rear wheel. I installed new rear disc parking brake cables since the old cables weren't in decent condition. Once you have them, they will connect up to the existing parking brake cables/mechanism/adjuster.

The parking brake assembly on the disc brake rear has a set of small brake shoes at each rear wheel that press on the inside of the rear brake rotors when the parking brake is applied.

 

Awesome. I put all new hardware for my parking brake in except for new cables. Guess I will be ordering new cables here soon. Thx

 

Just make sure you order the correct length cables for each wheel. They come in different lengths depending upon the truck's length/combo. Take a measurement from each wheel to the parking brake connection point. The cable can be a bit longer than the old one but certainly not too short.
