^Interesting experience. I was mentally wondering the same thing this morning after seeing this thread.
Assuming the brakes get re-bled, assuming the ABS gets bled properly, and assuming it still doesn't work, I was thinking about the MC, and wondering if damage to these systems is more along the lines of a transmission flush, where the damage is already mostly done/setup for doom, and the flushing is the action that forces the issue, not the issue itself.

I did my neighbor's honda a week ago. We were redoing the brakes, so I suggested we flush it since we were in there. "They were done a year or two ago" he said. Reservoir fluid looked good, front caliper fluid looked okay. Rear- BROWN RUST CAME OUT BOTH!!!! His brake place was just changing the front. wtf!?!?!?!?

Fortunately I didn't know changing the fluid could potentially trash a MC. His car turned out okay. Now I know. I'm also a lot more careful spreading calipers on ABS cars compared to pre ABS to prevent backflow into the ABS. Glad my neighbors situation turned out okay. I'd feel just peachy explaining i'd trashed it.
