So I want to convert to disc brakes on my 46 1/2 ton and retain the 6 lug wheel. Plan on buying the 6 lug setup. Rear will be the stock drum brakes I want to put a master cylinder in the stock location. The stock pedals from what I see is 4.3:1. I bought a universal Chevy 1 inch bore master cylinder and planned on making a bracket to fit the stock location without modifing the original bracket. Has anyone attempted this in the past? Any issues with this setup?
Attached is a pic up the mock-up/templates. Plan to use the stock holes to mount bracket
I did something on my 46 very similar to what you propose. I used a different MC but the bracket I built should work in your situation. Shoot me an email and I can send you a short write-up and a bunch of pictures of what i did.
