Remaining problem is definitely related to the switch, but I don't think it's bent. Pedal has to go down about 1/3 of it's travel before brake lights come on, and before the cruise control cancels. I also get the "hill assist not available" message the first time I press the brake that far.
Car acts normal if I brake lightly, but they'll drag slightly when I push it the pedal enough to get the brake lights to come on. Then I can pull up on the pedal, and they'll release.
So in summary, there's (at least) 2 problems during this pad-change:
* All 4 brakes would lock up tight after initial pad change. Probably because I pushed the fluid back up the lines, rather than through the bleeders. Fix for that was ABS needed to be auto-bled via ForScan.
* Brake light switch A is faulty in some way. I've ordered a new switch.
That's happening now.
Fingers crossed nothing is bent. Doesn't look like it, going to replace the switch first.
