Well I'll throw my 2 cents into the mix on this one.
Disc brakes will work without a power assisted master cylinder. You would need to go with a 1 inch bore on the master to generate more pressure. Powered systems usually use a 1 1/16 master cylinder.
I am planning to put 4 wheel non-powered disc brakes on my 1940 gmc. I don't want the extra vacuum line to hook up.
Last week I ordered a complete front disc brake kit for my 1959 GMC 1/2 ton from The Filling station. This is a 6 lug disc brake kit with 12 inch rotors and master cylinder with booster and metering valve. The kit was priced right at $699. I will have to get some roller bearings now for the original hub for another $150 or so, bend some lines, etc. I chose to go with the power disc brakes on this truck because it has factory power steering. I thought it would be nice to add that option.
