Update: my rear brake pedal doesn't feel anything when cycling the ABS. The rear caliper still is not bleeding. The rear reservoir is still full so it's not taking fluid into the system at all. I disconnected the brake line going into the caliper and nothing came out, so the line is essentially empty. I pressed the brake pedal with it disconnected and nothing came out.
So even though the brake pedal is moving something is blocking the fluid. Again, all symptoms seem to point to the ABS unit. Just for grins I hooked up my MightVac to the caliper bleeder and pumped it up to about 20 psi, I removed the cap from the reservoir and wedged the brake pedal down to see if I can gravity bleed it. This usually works in non-ABS systems, but since the ABS unit is uphill from the rear master cylinder, I'm not sure this will work. But anything is worth a try.
I'm open to more suggestions. Replacing the ABS looks expensive and time consuming.
