I did this on my 81 f100, the only hard part is that you need a power brake pedal. The pin for the rod sits lower (I think) than the manual pedal. The pedal is pretty easy to swap, there is a couple spring clips and the rod slides out. If you have access to used parts (wrecking yard) for the pedal it’s a worthwhile swap.

 

EOTZ-2455-A .. Brake Pedal-Use with M/T & Power Brakes / Obsolete

1980/83 F100/350 & Bronco.

No Ford dealer or obsolete parts vendor has any.

 

 

With or without Power Brakes has nothing to do with the "Brake Pressure Differential Valve" as it's the same for both.

The same valve (EOTZ-2B257-A) was used 1980/83 F100/150 & Bronco & F250's under 8,500 lbs. GVWR

 

I did the same to my 81 F100 using parts from my parts truck.
Because of swapping brakes on other makes I knew to swap pedals and sure enough the power & non-power are different on our trucks.


I swapped the whole assy. as both trucks were sticks only difference was power/non-power brakes.
I don't remember what one is power or not.




I cant remember on the lines as I could have used the power lines from master to the valve on the frame. If the fittings are the same you may just need to bend them a little to reach the master that is out farther from the fire wall.

I have not driven the truck yet but don't see I would have any issues.

The master cylinders are different, but the only thing I see is the threaded port sizes. The bores are both 1 inch. The only problem, if someone down the road needs a master cylinder and they get a power master cylinder, the lines are not going to fit.

 

When I did my swap I did not look that close to that as I took every thing from the rolled over parts truck as it all was working when it rolled.

With that said I guess I took the power master lines to use on my truck.

I would say get everything from the junk yard: pedals, booster, bracket(s), rods, master & lines.
Then what you may want to do is get a rebuilt booster & master, sometimes sold as a complete unit, and use the JY parts as cores.
