I used front rotors from a 1979 F-150 and front calipers from a 1980 Chevy K10. Speedway motors carries some brackets that you can use, but I got a set from Unlimited Offroad. I'm sure there are others out there that carry brackets.

I think explorer rear discs work, just need to make or buy a spacer.
This is my plan once I get the bronco driveable.

Yes you have to drill out the backing plate for the larger bolts and there needs to be 1/8" spacer or if you are getting new shafts order them with the correct brake offset

ok this seems a little much to me. 300.00 and you get no hoses,no calipers,no pads and a custom rotor they drill out so I cant just go to the parts store for a replacement?

I think I could do better than that by just buying some brackets and getting the rest at the parts store.

Somewhere in one of my build threads I had what I did all listed out. I used mid 70's chevy front calipers and 90's dodge front rotors and weld on brackets.

1975 Chevy 1/2 ton 4wd come with pads
Calipers #142-2022 and #142-2023

Parts Plus #'s

1995 Dodge 1/2 ton 4wd......because these fit over the stock flanges of the shafts with no grinding
Rotors P76447

1975 Chevy 1/2 ton 4wd
Brake Hoses #BH36761

Little Spacers from Lowe's....cut to fit inside the rotor where the lug stud slides through to center the rotor over the studs
the spacers are "Hillman" no part number but they measure 1/2 x 5/8 x 1
found them in the little hardware isle in the chest of drawers
If I remember I had to grind the brackets a bit to fit the tubes, but for the price it wasn't a big deal, but that was like 4 yrs ago. I have done ALOT of things since then

I did the speewaymotors weld on brackets. I had to drill out the stud holes on the 78 f150 front rotors to fid the studs, then I run moser shafts so I had to grind down the outter flange to allow them to fit inside the rotor. Not much, just a hair.




When you go to weld them on, hook up air to the bleeder valve. This will clamp the pads to the rotor and you know its flush..
