Do you have your PCM recalibrated for different size tires or gears?

Is the brake master cylinder full? If not, the fluid may be sloshing at WOT and the level sensor may be turning the light on...

Brake fluid level too low is my first thought. Unless you have something going on with the wiring to the park brake.
