Theres a TSB out there 03-05-25-007d that says its caused by an increased air gap between the wheel speed sensor and hub reluctor ring due to rust and debris build up on the sensor mounting surface.
Hopefully someone can post the TSB, for some reason I cant copy paste it.

On my '98 Silverado the mounting surface below the sensor began to corrode, causing the sensor to lift. It only lifted like a millimeter, but enough that the sensors would have issues reading. I never had an ABS light go on, but I had issues at stopping speed where my ABS would go off (pulsating pedal). This was because my front sensors could not get a good reading, didn't match with the rear wheel speed, thus a time ABS should engage. I used a wire brush to clean up the mounting surfaces, worked like a charm! Before doing this I put in a paper towel to the hole to plug it up so debris wouldn't go inside it.
My 97 would get like this too, did as swhitey did above and cured it, for a while then had to re-do it about every year year and a half.

If you feel like it, CAREFULLY pull the sensors out, and go from there.

I have a 1999 Chevy Silverado 1500 Z71 and am having issues with my ABS. When coming to a stop, the ABS will kick in when under 10ish mph. I started to happen after I changed my driver front wheel bearing. It was a cheap Ebay bearing, so, now, about 3-4 months later, I bought a new wheel bearing and installed it today to see if it changed. Nope. When I changed it a couple months ago, the ABS & Brake light would come on but reset when I would shut the truck off. The ABS pump is not having the typical issue where it runs non-stop, but it kicks in for no reason.
Any chance you have the ABS codes?????? Cxxxx.................. Could be the control module
