86 URq with no barkes

[Huw Powell]

this is a long shot, but maybe when you pushed the calipers in, the
fluid going "against" the cups in the master cylinder wrecked them?  Now
they do not "squish" the fluid when you press the pedal, they just move
thru it?

I would try opening a bleeder and pumping, such as you can, to see what
happens.  Even the prop. valve bleeder, since it's easier to get to, to
start with.
