1996 R1100R brakes Saga continuing

So,
the new front pads and Spiegler lines are in. Rear pads looked quite good.
after 3 days and over a liter of fluid, still can not get to the normal response. Rear lever is soft/spongy, even after both ABS and caliper bleeder not producing any air bubble (both with the Vac pump and brake lever).
Got to the hard lever in the front, but now the front brakes are stuck solid.
What I am doing wrong?

First a few questions:

Were the original lines deteriorated on the inside ie: bits of rubber in the old brake fluid?

Did you remove the pistons from the calipers and blow everything clean?

Many times bits of rubber inside the calipers will clog the banjo bolt and not allow fluid to return.

Did you bleed the F & R nipples at the ABS module as well?

Rear systems are hard to bleed. Use a Mity-Vac. Harbor Freight has a reasonably priced knockoff.

I recently had my front brakes lock up. Problem was the ABS module. If your brake lines deteriorated and you rode it like that( without knowing of course) then you may need the ABS module refurbished. Module master in Idaho did mine and it works great. I think it was about $400. I highly recommend them. I'm not paid by anyone either lol.
