[do we have any diagnostics that can be applied to the ABS?]

I swear, I'd still wanna verify the brake hoses inner lining has not de-laminated
and/or started acting like a one way valve internally.
(How old are the hoses ,and from whom did you acquire?)

The Hit man is/was correct.If pads/rotors are not properly "seated"against each
other problems result.Except for Ceramic pads,the bedding in process is an
increasing speed use of the brakes (without ever coming to a complete stop).
[But,if you're reusing rotors they must be "deglazed"as in X man's instructions]
(Bedding in is the transfer of materiel from the New pads to the rotors surface,
AND cannot properly be accomplished without a fresh rotor surface.)
I would have to agree with you..fluid transfer pressures...

Like today for instance.. When I left this morning, my pedal felt sturdy, solid..it has a little bit of play in the beginning and then you pushed into it and it was solid all the way to stopping...

Later on in the day it wasnt as this...It became kind of soft in the middle..

When I came home today, I pulled into my driveway then drove in to the garage ( <10mph up the drive) and when I braked the fronts groaned something awful and the ABS kicked on. That seems to be the only time it comes on when I'm trying to come to a full stop when traveling at a low speed.

When I'm going 20+ the ABS doesnt do anything it shouldnt and there is no squaling. Just Low speeds to stop...

I'm wondering if the issues are tied together? I.e. not having enough "stopping power" makes the ABS think it should take over?

Does any of that sound like Master Cylinder issue?
