Skid/Wheel hop of front wheel when hard braking just before the ABS kicks in, ???

To close the loop on this, I just did a front brake rotor replacement, and it resolved the issue.

Longer version: I just did some maintenance over the holiday break, and one of the things I did was replace the front rotors. They were both down to <25mm (new 28mm, replace at 26mm for 2000S). The pads had >10mm so I left them and just replaced the rotors (odd?) I went ahead and did a bedding procedure (I did about 7 or 8 60 to 15 decelerations and then drove for about 15-20 minutes and then parked without ever touching the brakes.) Later on a subsequent drive I decided to do a quick stop and activate the ABS and the issue did not re-occur. Problem solved

I'm thinking the fresh brake fluid was the main thing that eliminated the issue.

Could be; I did have a full brake flush done (with ATE Super Blue) in Sept 2013 but the mechanic (I was short on time and had never done bleeding/flushing before so opted to have the mechanic do it) only bled the outer caliper bleed screws and he used "gravity bleeding", when I bled them this time I did both bleed screws and I got some "green" fluid (blue/amber mix maybe?) from the inner bleed screw along with a handful of very tiny bubbles...
