ABS probem after LS1 brake install

Hello-
I've just swapped a set of 98-up front brakes on my 97 Z. They work great with one exception.
As I creep to a stop, the last foot of movement, the front ABS activates. I get a low traction light, the pedal drops slightly, and I can hear the ABS motor working. No way it's actual slip, we're talking 2 mph and under on dry pavement.
All I can say is WTF? Do I need to bleed the ABS module? I topped off the master cyl as I did the caliper swap, and only had the brake lines unhooked for 1 minute per side.
I even re-used the original hubs.

Anybody had a similar experience? Any advice?
Thanks!

Might be a bad ABS sensor causing that problem.

I had to change the two front ABS sensors on my truck this past winter and it was doing a similar thing - not sure how'd you'd test to make sure of that though.

Update! Fixed!
Rechecked all connections, re-bled the ABS unit, no improvement. Swapped the 98-up hubs onto the car. Problem solved, it had a bad ABS sensor in one of my original hubs. Thought about it for a minute, then remembered dropping one of the hubs off the workbench. Guess what, drop marks on the bad hub. I'm my own worst enemy But it's fixed
