And I'll stand by what I wrote. It is a simple mechanical pump,
with a separate storage tank that sends fluid at full pressure to each
wheel, when that wheel's speed sensor triggers it, and not to the wheels
or axle that is spinning at less revolutions, spend some time and figure
out how it would work.

What part of 'so the wheels don't lock up' do you not understand???
I remember when my Dad bought a new wagon and he was really proud of the
anti-lock rear brakes, especially for winter stops.
No more sideways slides, just pushes through intersections because you
couldn't lock the rear wheels with a rear wheel drive automatic.
He learned real quick to use neutral to stop which is the big downfall
of the modern 4 wheel ABS.
The 'only' reason for the proportioning valve is to provide rear anti
lock brakes.
It serves no other purpose.

Mike, that isn't ABS per se - it's a simple proportioner valve that
modifies the amount of braking you can get to the rear wheels. On my
MJ, there is a linkage between the axle and the bed that senses the
load as the distance between the axle and the frame and allows more
braking on the rear end as the load increases. Damned thing must work
- I forgot to connect the link rod when I changed the diff fluid one
day so the rod was hanging all the way down making it think it had a
full load. Locked the rear brakes as soon as I hit them to remind me
to hook it up. It knows zilch about wheel rotation/skid so I wouldn't
call it a real ABS.
It's also a PITA to bleed the rear brake lines if you ever get air
into the proportioning valve!

Mike, that isn't ABS per se - it's a simple proportioner valve that
modifies the amount of braking you can get to the rear wheels. On my
MJ, there is a linkage between the axle and the bed that senses the
load as the distance between the axle and the frame and allows more
braking on the rear end as the load increases. Damned thing must work
- I forgot to connect the link rod when I changed the diff fluid one
day so the rod was hanging all the way down making it think it had a
full load. Locked the rear brakes as soon as I hit them to remind me
to hook it up. It knows zilch about wheel rotation/skid so I wouldn't
call it a real ABS.
It's also a PITA to bleed the rear brake lines if you ever get air
into the proportioning valve!
