I am just about to do this conversion, as outlined in his how-to essay posted in the Tech Article section. No rear discs for now though.
It is going on a '74 F-100 with an 300 inline-6 and MANUAL brakes. His instructions only discuss the conversion in terms of '78-'79 Broncos, but I think I can reasonably assume that earlier '70's Trucks will use the same principles as they (trucks) are pretty much the same as the Bronco from the doors forward ((right?).
So that being said, I will be using a 1974 Power booster/Master cylinder (matching the parts to the year of the truck it is going on) and 1974 T-Bird calipers (also matching up the same year's parts). I am also going to assume that my current brake pedal linkage will work in the upgraded setup, including interfacing with the new Power booster setup (right?).
My major question involves the front brake lines...
Mr. Cabral says in his tech article that the existing banjo bolt-style on the truck is necessary to retain in order for the hose to clear the kingpins. However, the T-Bird calipers use the conventional screw-in style hose which will not clear the kingpin. In order to adapt the banjo-bolt hose to the screw-in style calipers, Cabral suggests using a series of AN-fitting adapters. But after you add up all of the fittings that you need, you are pretty close to having some nice braided lines made up custom for you...
Can I circumvent the need to hodgepodge these lines together and have some lines made which work right out of the box. Or does this particular application necessitate the use of the fittings no matter what I do. I have never removed the calipers of of this particualr vehicle, so I can't easily picture what needs to be done.
I did this style swap a few years back and used 77 lincoln front calipers. They are about 3.1 inch pistons vs the truck 2.9 inch . Be sure to measure the car caliper to make sure. This may be specific to those cars equipped with four wheel disc brakes. As far as the brake lines : The banjo bolt will screw directly into the car caliper. The problem is there is not a flat surface on the car caliper to seal on. So I put mine in a mill and machined a flat like the truck caliper has. Other than the piston size and flat they are the same casting . This will be very evident once you take the two side by side . If you or a buddie has access to a mill or can have it done cheap somewhere it is a great alternative.
