How did you address the pressure differential between the old
hydraulics
and the new? There is a combination valve in the system designed to
limit the pressure to the rear drum brakes so they cannot lock up
during
a panic stop. If they do lock up, you will swap ends faster than you
can blink.
The brake master cylinder also sends different volumes of fluid for
drum
wheel cylinders vs calipers. The, or some for sure, master also has
check valves for drum brake fluid flow that can jam disk calipers
'on'.
I know 100% for sure that a master cylinder for drum brakes will 'not'
work for disk brakes on a CJ7 or CJ5. It 'will' jam the calipers in an
'on' position, I have seen it happen several times with sloppy parts
counter persons giving out the wrong one or the wrong one in the right
box. So if your gas mileage starts to drop....
Just a heads up for you.

Final note:
Over the weekend, I drove up to visit my dad. Up there on the 45th
parallel, the secondary roads are still completely snow packed or
iced-over, which gave me several op****tunities to mash on the brakes
to see how the Jeep tracked. It glided completely straight on both
snow and ice.
So, I do not think there's an issue with using the stock XJ master
cylinder and pro****tioning valve with the Liberty rear discs.
If I experience anything different on dirt, sand, or dry pavement, I
will post it here.
