1966 f100 disc brakes

finally talked my brother into an early car he is a toyota landcruiser guy but loves his f 100 except for the brakes .it is original 6 cyl but he wants to fit a 351 .my question is what disc brakes and booster will fit the 66 as we have a big swap meet coming up and finally we can go hunting together.he wants to keep the original wheels (widened)so it has to be the same stud pattern. thanks dave

 

I believe brakes up to '79 F100 will swap. The spindles will mount to the '66 axles. You just have to get kingpins for the donor vehicle application. I don't know what the differences are between kingpins, I just remember an article I read many years ago that said you should buy kingpins to match whatever spindles you're using.

The brake booster is a little harder. There was a thread on here a month or two ago about that subject. I seem to remember a few people had found one that would more or less bolt on. The '76 one I used needed to have the rod lengthened that went to the brake pedal. I had a welding shop cut mine and splice in a piece. If you do have to lengthen this rod, keep safety in mind. Some half-a** engineering and welding can result in failure, no brakes, kill people, etc......

I've seen a few trucks that had the proportioning valve mounted at the booster with a little bracket. If you come across something like that, it might make your brake line fabrication a little easier. I ended up mounting mine to the frame rail under the cab. Either way, you have to bend up some brake line to get everything connected.

I think it's a swap that's well worth the effort. I was very happy with mine when it was done.

 

thanks belvedere .i know its a while ago but i am talkin 66 spindles what disc brakes adapt to it taking into consideration king pin inclination etc

 

As mentioned, it's probably simplest and cheapest to swap in the whole disk brake setup including the spindles from a later model F100. The parts should be easy to find in the junkyard and you should be able to get new pads, rotors, etc. at any auto parts store Here's an article on the step by step process. http://www.ford-trucks.com/article/...onversion_Guide_For_19651972_Ford_Trucks.html

 

thanks stuart great response

 

any f100 or 150 from 66-78 will work i swaped beams and all from a 77 into my 66 as far as the booster the same is true be sure you also get the proportioning valve
