261fun.... there is a lot of good information on this thread for you. These more experienced guys are making a lot of great points on your original question for you to consider.
I recently went through the same delema as you.
I have a 50 ½ ton and I installed the Performance Online front disc brake kit on my truck. I went
without the booster for now. My truck is still on jack stands so I won’t know if I regret not installing the booster.
The pic cleatis posted is great, I think that set up is on a suburban.
On my 50 pickup that booster that cleatis is showing would
not fit without modification of the trucks original trans crossmenber. The whole set up would be too long. If I had gone with the booster I would have had to remove the original trans cross member and purchase a aftermarket one and move it to the rear. This may not be the case for your year truck but it is something you can look into.
I think you said you are set up for drum/drum right now. Your current dual master cylinder may not work with a disc/drum system. You may have to purchase a new dual master cylinder or at least add a prop valve. If you look at cleatis picture you will see the prop valve mounted right under the master cylinder.
The brake and clutch fit perfectly on POL kit I bought.
You may have to run new brake lines, at least to the front.
You may find out while you’re doing this work that your kingpins need replacement.
You may have to add residual check valves in the your brake lines
Your current wheels probably will not fit the front disc brakes. Depending on what you’re running on. The wheels I had on my truck did not fit the front brakes.
Picture of my wheels that do not fit after disc brake upgrade There is a lot to consider if you’re going to do the upgrade. Weather you go with a booster or not there will be some head bumping and head scratching work involved. But when you’re done and your knuckles heal I’m sure your be satisfied and your be able to stop your truck better when that little honda cuts you off.
