Has anyone done that?  Thinking of doing that and would like to call on anyone who has and what problems I could encounter.

I can't speak for the booster but can say that I have front discs and rear drums on my 55 Bird for the last 25 years. My pedal is hard and the effort is way less then the original with all drums and stops way better. So I would say try it without a booster and you can always add one if you need to. You can always size the master cylinder and calipers to increase force also.

I bought a front disc/power booster kit from one of the Thunderbird supplier (they retired, I think Hill’s acquired them) back in 1999. It used a disc/drum dual master and the booster on the front disc only. I don’t recall if there was a different rear wheel cylinder (for balance adjustment) or if it would be different with the front booster. But most of the bird suppliers would know.

Vic, glad to hear you are happy with your brake setup. I bought Wilwood 4-piston Dynalite calipers and 1 1/2 drop spindles from Dave (Drop em Stop em), Wilwood 15/16ths master/w proportioning valve, retaining OEM 11" rear drums, but no booster. I'm still working on put my 55 back on the road, but it sounds like I'll be happy with my brakes. I do intend to put automatic adjusters on the rear and can provide parts list for same if you're interested. PM works for me.
