I've had several Fords that have had problems such as you have described and the "cure" was to disassemble, clean the slides, chip off any rust, lube with high temp grease then reassemble. My '79 Mustang needed to have that done every 12-15 months. The most costly one was my current '06 F350 which cost a pair of calipers, rotors and pads. Now I 'fix' it yearly as well.
And that proportioning valve is probably not needed.
Also, check the MC for a resid check valve tooDave W

Some of the Ford and early Corvette MC had residual/check valves at the outlet.
While I don't know what you have for a proportioning valve, I think that I would try and remove what you have and install an adjustable version. At less then $40 and some tubing might just make a difference. I have Wilwoods on all four corners of my '31 along with one of their adjustable units - and it's wide open at present. And the brakes - the rears on mine are 12" with the fronts 11", so for all intents I have more brake power on the rear then the front, and they stop just great - straight line and quick - after about 6 different break in cycles which was a thread of mine last year.
That three hole valve is called a 'hold off' valve by ECI - which I found on an earlier car to be a POS. Is this the one?
As far as which MC reservoir - the largest always goes to the front. This means if you mount the MC under the floor, it will usually be 'backwards' and you need to make plumbing to adjust for thatDave W
