Specific questions on the rear disc brake conversion compatibility for my Bronco. Here’s a little background for you…... I have a 1974 Bronco with the medium duty axle and large bearings (MDLB) and 10”X1.75” drum brakes. I believe the axle flange style is referred to as the “Torino Style”, but I’m not 100% sure on that. I have acquired a complete rear brake disc setup from a 1997 Ford Explorer. I’ve read a bunch on this specific conversion but wanted to make sure I’ve got it correct before proceeding. If you guys could give me some feedback on the questions below, It would greatly be appreciated.
Is the swap a 100% bolt on for my 1974 Bronco and the MDLB with the parts I have from the Explorer?
I know the Explorer rotors would have to be redrilled to the 5X5.5 pattern. What is the best way to do this? Maybe lay the drums on the rotors to mark the holes and drill it myself? Has anyone done this without taking it to a machine shop?
Axle flange offset issues? From what I understand, the 74-75 medium duty large bearing axles have the correct 2.5” offset. Is that correct? If not, do I need to order shims for the axle bearings to correct the difference?
From what I’ve read, I may have to grind the outside of the axle and the inside of the rotor hole to get the rotor to fit over the axle and parking brake shoes. Do I have this correct?
From what I understand, the explorer parking brake system can be used for the Bronco. What modifications to the parking brakes would need to be made if any? Do you use the explorer cables or the Bronco cables? Etc…..
What master cylinder would I need to run with disc on front and back? I currently have the stock drum master cylinder with no power assist.
