1970 2wd disc brake conversion

Ok, so I just started getting my baby back up to speed and I am switching her over to front discs brakes. I have a few questions...

What parts will I need to do the conversion?

How much will it cost?

What would be the "best" option to take?

Can I use a 4wd setup on my 2wd?

If I wanted to pull parts from another truck, what do I need to use?
....also what year?

Help me!!!

Go here for your answers.....https://www.ford-trucks.com/forums/4...-for-info.html
Scroll down to post #4.
Can you use 4x4 brakes on your 2x? No, they are not interchangeable.
You can go aftermarket if you want but it is more expensive.

Then I guess I'll assume that I need to find a 2wd 73-79 for parts?

Difference?

What is the difference between the 2wd and 4wd conversion kits?

4X4's have completely different spindles, if your truck is a 2 wheel drive the easiest and best way to do it is buy a 73-79 2WD donor truck. The suspension from the donor is a complete bolt in. Better than a conversion kit in my opinion. That way you have every bracket, line, etc. Then part out the rest of the truck and end up making money in the deal. You can score the power steering also if you so desire. I can always find a couple of these on Craigslist for $500 or less.

I have a 71 F250 that just finished the conversion from drums to disc. I bought the larger parts from a salvage yard of a 75 f250 and had to piece the rest from different parts houses. The setup is a for a heavy duty system, so it took a while to find all the parts. In the end I spent around $750. That is cheap compared to a conversion kit. It stops on a dime effortless. Be aware the if you are limited on knowledge on how brakes work and their instalations this could become nightmare job quickly.

Here is the list of parts I used:<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
· used calipers & mounting brackets<o></o>
· new pads<o></o>
· new seal for the calipers & mounting brackets<o></o>
· new slide pins<o></o>
· new flexible lines<o></o>
· new rotors and wheel seals<o></o>
· new in-line adjustable proportioning valve<o></o>
· Brake line tubing and fittings<o></o>
· wheel bearing grease <o></o>
· brake fluid<o></o>
I re-used some of the used miscellaneous hardware and the bearings (they were in good condition)<o></o>
If you use a new in-line adjustable proportioning valve, you may need to make a brake lines or modify an existing ones.<o></o>
I have pictures, just not sure how to post them.
Good luck

Would it matter if I found parts for an f250 and put it on my f100?

Not a good idea unless you want 8 lug 16 wheels and heavier components.

Definitely not a good idea. only a few miscellaneous parts will be the same. Everything else is bigger and fits different. Cheaper for an f100 too.

For an F100 most of the parts house should have any replacement parts.
For my F250 most things had to be speacial orderd.

i did the same conversion about 3 years ago i used 2wd spindles from a '73 f-100. i called around a few junk yards and found them had them sent to me only cost about 100 bucks for them. i ordered new kingpins, rotors, calipers, radius arm bushings and springs and shocks all from napa. the cost wasnt too bad but its worth having all new parts. i had an extra proportioning valve from a 76 f-350 so i used that. after having a friend with a machine shop put the new kingpins in it was really simple to convert.
dont forget about toe angles because with the new set-up they will have to be adjusted! it's real simple to do with some chalk and a tape measure. after i was done my truck handled like it was brand new again. its been 3 years since i did this conversion and it was the best thing i've done to my truck!

Think I'm gonna do this for my 72?

To the guys that have done this conversion how many just replaced the spindles? I've heard a couple of stories of people saying if you get a 73-74 donor you won't have to get spindles and i beams is this true?

Thanks!

Richard

It is easier to get the whole I beam assembly because then you don't have to mess with the king pins unless they are bad. You will have to get spindles either way. 73-79 will work for the donor regardless of which way you go. 75-79 spindles just take a different king pin. Just make sure you get the steering linkage out of the donor too.

I have installed spindles from a '77 on my '69 and currently have kingpins for a '69. Works perfect.
