Is it possible that a ford with rear disc brakes would have a caliper bracket that would bolt to the axle flange with minimum mods bolt to the front spindle of 53-56 F-100? 3 7/16 by 3 7/16

Very unlikely. And most of the Ford rear disc brake use a drum Emergency brake assembly that's part of the caliper bracket. Trying to use the rear bracket would just make more work over just making a new bracket.

tazcliff,
Check here at ECI for part of what you are looking to use.

ECI Early Disc Brake Conversion Kits

Their kit for the 48-52 Ford pickup uses the later Ford pickup 5 on 5.5 rotors and large GM calipers. It appears to be a flat plate bracket to bolt to the spindle. You could buy the bracket/bearing kit without the rotors and calipers and then cut a new bracket for whatever Ford rotor you can find to work with the late for rotors. This will involve more work on your part to engineer the all-Ford brakes.

That's basically what I was suggesting. By buying the basic bracket kit you'll get the parts needed to use the rotors. And who knows you might be able to sell the brackets and get some of your cash back. That is if the brackets are not usable. You might be able to modify them to get them to work with the Ford calipers.

What I meant to say was you could buy the bracket/bearing kit and cut a new flat plate bracket to use whatever Ford CALIPER you wanted to use with the late Ford ROTORS. The kit contains bearings and spacers to use with the 48-56 spindles and the late Ford rotors. You need those items to use the rotors with your spindles. You could then plasma cut new flat plate brackets to use with your selection of Ford calipers. It can be done with a little thinking, parts chasing and engineering.

Yes I know, the rotor adapters are the only reason to buy the kits.

The problem with making and selling kits is the liability. If for some reason there is a parts failure the person selling the kits could be sued. And for me I don't have a plasma cutter or any other fancy tools. So there would be a lot more time required to make the brackets. By the time you figure in the material cost and time invested there is very little profit to be made. If you had a way to mass produce them then it would be worth considering.

That is a business waiting to happen! If you decided to persue this idea, I for one would surely be interested in the final product.

I can understand the liability involved. I'd even send a release for a ford kit. Cest La Vie.

My locale is the far Eastside of Tucson. My truck is a 48 F1. I'm a darksider because it has a Dakota IFS in the front, installed by Industrial Chassis in Phoenix.

For the bracket talk to Steve at Industrial Chassis. He has the experience and the computer controlled 2-axis plasma cutter to cut them out. He may be able to help you out. Phone 602-278-6800.

I have a big bearing 9 inch that I want to convert to disk. Just by chance I got next to a late model 8.8 with disk brakes today (mustang GT) and took some measurements.

The axel to flange offset is the same between the two.

The caliper mount plate is flat stock.

And of course the bolt pattern matches my 9 inch (5x4.5)

Even the rotor inside diameter is large enough to slip over the 31 spline axel flange.

The only problem area I noted was the flange bolt pattern on the mount plate, the 8.8 has a 3.4 x 1.6 bolt pattern and the 9 inch has a 3.56 x 2.0.


So it looks like by having two new mounting plates made to match the 9 inch flange pattern, the mustang GT rear brake should bolt right up, they even have manual E brake (cable), not drum.

This may help the guys like me who are converting to the narrow lug pattern but for those of you who want to keep the wide lugs all I can say is see if the rotors can be re-drilled to match.

I believe the Explorer is a simpler swap for rear disc brakes. It just requires a spacer on the axle shaft. Other wise it's a bolt on swap. But I pretty sure this thread was dealing with front brakes not the rear.
