About 2003 I started getting into 4-wheeling. I had a 78 Bronco I was building. I upgraded the axles to a Dana 70 rear and 8 lug Dana 44 front. I also did every other brake upgrade I could find on the internet including a different master cylinder and booster. I never was happy with the brakes. I could adjust the rear brakes and it would be OK for awhile, but not for long. I felt like I had to push the pedal through the floor to get it to stop when on the trails. Finally I ordered a disc brake kit for the rear and all my brake problems went away. I paid over $400 for that conversion. I thought that was way too high so I started putting together my own kits. Now I am selling a complete bolt on disc brake conversion kit for most axles for only $315 including shipping to anywhere in the USA!
