Ford Juice Brakes

I am guessing this is the place to ask about brakes as well as wheels and tires. I have a brake set up that came with a car that I bought that I think is referred to as Juice Brakes. Forgive me because I am kinda new to the older car stuff. Anyway, I am wondering how these brakes work and if it is better to go with a disc set up. I am building a 34 Ford truck, but it is not going to be original. I know from what I have read on here and other places that alot of guys like to use them for the original style. The set up is in excellant shape and has brand new pads and rebuilt cylinders, but I am leaning toward disc. Any suggestions....

Thanks ,
Roy
