01 Tahoe Brake Warning Lights

[bowtiedoc]

For the last year, while driving and not even applying the brakes, the red Brake and yellow ABS lights pop on. No loss of brake performance, park brake is not engaged. When I shut the truck off and restart, the lights go out and pop on randomly. Once or twice a day or once a week, no real pattern. I did have the front bearing replaced, but made no difference in the lights popping on.

Any ideas?
