Hey Viper, an option is a "manual" Baer M/C setup with a disc setup. I was VERY hesitant to try a "manual" system with a 4 wheel disc setup . . . for some years, but I did it and I'm "relatively" happy with it. Let me explain . . .
I have a "manual" pedal setup and not the power unit on my '65. I'm talking off what I remember from 3 years back, so feel free to verify all of this. The '65 model had different brake pedal setups for "power" and manual brakes. The manual brake setup has a longer fulcrum (and it IS long) so you have lots more leverage. Putting that setup with a good manual M/C (like the Baer) makes for relatively light (but long throw) braking. Mine is super easy to push. My (really small) wife has no issues with it, either, and I mean driving around town for extended periods driving.
Now, here's what you need to do first, though. Get with Baer and let them walk you through sizing the brake pedal fulcrum and what size M/C to use (it's easy). Then figure out how aggressive you want the pedal force to be. Getting back to my "relatively" comment . . . I went way too soft on the M/C (bore size wrong), and I don't have enough force to stop in an emergency satisfactorily. I'm going to swap out to a higher pressure unit which will have a heavier pedal force, BUT, even a little heavier won't be bad at all for driving around extended periods. I'll also, most likely, have shorter throws on the pedal, which will be nice.
I've been 4 wheel disc since 1994, and I've always been on the lookout for something "better" with regards to M/C and booster combo. That being said, TENTATIVELY, I think the Baer setup I have (and will have better) is a great way to go. I'll keep you posted on how it goes. Gotta' sell a house, first, and then she's going in for some TLC.
