'49 F4 Disc Brake Conversion
Here are some photos of the disc brake conversion for my F4. I am using rotors and calipers from a 2005-2016 Ford F450- F550.
The rotor is 14 1/2" diameter and 1 1/2" thick. The caliper bracket is 1" thick plate. I still have to machine the plate to bolt the rotor to the hub.

Joe, I want to make sure mine works correctly first, but that is something I might consider if there is any interest. I don't know if there would be any DOT regs or anything else that I would have to comply with.
Thanks, Mark

Thank you, Scott. I have the booster and master cylinder that I am going to use. It is from a 2012 F450-550. I still have to build the bracket to hang it under the cab. It is a lot larger than the original so, it will have to mount farther toward the rear of the truck. I will probably cut an access hole in the cab floor in front of the fuel tank. I will have to adjust the seat all the way forward to fill the master cylinder. I'm still considering mounting the reservoir either under the seat or on the firewall and connect it to the MC with hoses.

For somebody like me, I could get 10 lug 19.5 wheels and keep my tires and help offset the cost by selling my 'good' drums as well as the shoes, backing plates, wheel cylinders etc. Of course I would probably be forced to change the master cylinder too.

Joe, I am keeping the original 5 hole pattern as I already have a set of 19.5 wheels. I am using the 10 hole rotor so the bolts for the rotor won't interfere with the 5 bolts that bolt the drum to the hub. I will use the drum mounting holes to bolt on the spacer that the rotor will bolt on to. If I had realized earlier that my front drums were not turnable, I probably would have changed the rear axle to a '70s 1 ton axle and modified the front to use 8 hole hubs and disc brakes from a late '70s 1 ton also. Then I could have used 16" tubeless wheels and tires. Although, adding the cost of changing the rear axle, I may not have saved any money going to the 8 hole wheel. I know I would have had a similar amount of machine time modifying the front for the 1 ton brakes.

Ray, The caliper bracket for an 8 hole conversion on your truck would be very similar to the one I made but probably a little smaller. We could use a late '70s or early '80s 1 ton hub and rotor assembly and modify the caliper bracket design to fit the 1 ton caliper. There is a new member that posted in Oct or Nov on the build thread section, a couple of photos of a conversion just like this on a '48 F5.
Thank you, Mark

Steve, Hopefully in the next couple of weeks I will have my front brake conversion finished. I will try to get what the cost might be. I could machine the caliper bracket, rotor spacer and the banjo fitting to adapt the brake hose to the caliper and supply a parts list for the brake parts to be sourced locally or at Rock Auto.
Thanks, Mark
