Oh man what a job! My hat's off to you on that one.
Now I have another thing to check this winter. I rarely even look at the ABS pump. I'm afraid I'll give it some bad ideas if I start looking.
Hey, wait a minute. If our lines are s/s, how the heck did they rust thru in the first place? They have to be some cheap alloy or pure steel? Real s/s doesn't rust if it is at least 18/8 or better.
How did you bleed the ABS pump? Did you have a TECH1 or 1A?
