Thread: Ford 9" rear end/disc brakes donor car

Tweet

What is the easiest andcheapest way to set up a Ford 9" rear end with disc brakes.
1) What is a good donor car?
2) What width do I need for a 32 Ford?

Ford Motorsports has a conversion package from ford explorer around 300$ with internal parking brakes

Does that give me the correct width?

Try to find one out of an early Ford Bronco. They are just the right width. The website below is a good reference for 9-inch Ford widths.

There are a couple vendors on EBay offering Disk Brake conversions. Some are just brackets and you go to Pick n pull to get Cadillac Eldo calipers and Crown Vic rotors. Others are more complete and just bolt on. Summit Racing also sells a complete kit as does Stainless Steel Brakes. If you do a Google search you will find lots of brake options, once you locate an axle.

Thanks. Great website. WOW. Still trying to find a donor type car for the dics brakes, Lincoln maybe?

Thanks StuCool. You responded before I did. Good input. Also the width of early Bronco - 58" at wheel mount flange?

Great contribution rumrumm, I've added it to the 9" article on the Crankshaft Coalition wiki on another forum....

Some Lincolns from the 70's had Ford 9" axles with disc brakes. I just got some off a 77 Continental Mark V to go on my 75 Bronco.

As mentioned before, Ford Explorers had disc brakes that would bolt onto the 9". I think the years are from 96 to 2001. In fact, the rearends of those Explorers were 8.8" axles which aren't too shabby.

If you want a Bronco axle, try www.classicbroncos.com. There are always folks with extras.

I have beat the heck out of my 8.8 that I installed in my Jeep. It has 4.56 gears and a Detroit locker.

Thanks Techinspector1. So much great information on these web sites. This is very helpful. Everyone is so helpful. Its all good.

Do your research well or it can get expensive - there are at least 3 axle tube flange bolt patterns along with the different bearings that they use as well as at least that many axle shaft protrusions. My rear diff is a smooth back '57, but like all of the very early versions through, I believe '61, has a "non standard" axle protrusion. I used a small bearing flange Wilwood setup then made up the proper spacers to fit the calipers to center of the rotor

For a fendered 32
Most rodders ... want a rear end that is 56 to 58 inches wide ... measured this way



Unfortunately ... the only Factory setups that narrow are the 57/58/59 Ford car rear ends and the 66 to mid 70's Broncos. The Broncos have the larger 5 on 5.5 wheel pattern ( think Ford pickup pattern ). They are 58 inches wide.

TCI sells their 32 chassis with a 56 inch 9 inch under them. They come from Currie and are narrowed units. NO stock 56 inch wide units ever came from Ford.

This is a 56 inch wide 9 inch under my 32 3W.



And now with the fenders on ...



This is a 58 inch wide 9 inch Bronco rear end under my 32 roadster



Both space the rim out about the same but the 32 roadster has 1 inch per side LESS offset than the ones on the 32 3W.

Some of the Lincoln Versailles ( 1979 or so ) are narrow enough ( with a proper back spacing rim ) and are 9 inch units.



Think fancied up Ford Granda

They come with factory rear disc brakes. BUT ... I would not use one because the brake parts are VERY difficult to find and VERY EXPENSIVE if you do.

Hope this HELPS
