5ktq rear brake problems

[Jay Rabe <j-yr-be@snet.net>]

    I am trying to get rear brakes working on an 86 5ktq (with abs).  I
put new calipers on the rear and a new brake prop. valve.  When i bleed
the brakes, fluid comes out solid, no bubbles.  Pushing the brake pedal
as hard as possible, you can turn the rear wheel with your hand.  I
cannot figure this out.  Fluid sprays out of abs unit when i loosened
the line out, but out of the caliper bleeder it comes slow.

Any ideas?
