I believe with 4 wheel discs you need a large bore MC cuz of the amt of vol needed to fill 4 calipers but first: they ain't pumping up? pedal effort doesn't seem to be doing anything at the corners? all 4 corners swapped to discs at the same time? and poor performance since then/day 1?

I'm hesitant cuz I have no first hand exp with 4 wheel discs (yet,got several planned) just what I read here. I did have a 1&1/8 alum dual bowl (w plastic reservoir) on a 65 dart with '76 A (2.75") calipers up front (ceramic iirc pads) & 10" drums on the rear with the OE drum splitter which means no proportioning & it stopped flawless but that was slow everyday driving around town & it would lockup the rears first if I hit em hard. A mismatch on paper but zero issues & no detectable pad wear either. I'd CONFIRM there's no air in the MC (first) or the corners (calipers can be tough to air out completely) then get the biggest bore MC I could find

I have the eldorado calipers on the rear of my truck, and standard GM front calipers. I have a 1.25" MC, which I believe is too big (now that I finally got a rear caliper that actually works).
I think I'll have to go down to a 1 1/8 or so to get more pedal travel and higher pressure.
MAKE SURE that you can't see any light between the pads and the rotor in the rear. If you do, you'll lose most of your pedal travel to take up that gap.
And yes, the ebrake has to be used occasionally to keep the pads near the rotor.
If you ever find yourself in a fair fight, your tactics suck.

That's true of any rear caliper that uses the caliper as an E brake as well, rather than a mini drum ebrake.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
