Hmm. I've never diagnosed one of these problems before. The abs and trac control makes me think one of the wheel speed sensors located in the hub/knuckles is messed up. But then the brake light makes me wonder if the pressure sensor to detect braking is messed up. I think its located on the master cylinder.

Do you have enough brake fluid? Maybe the sensor doesn't detect enough and set off the brake light?

What about your blinker fluid??????

the brake light is associated to the abs light, so you've got to diagnose the abs situation first. Check connections and sensors to ensure none are loose our disconnected. Check you brakes overall. Make sure you have enough meat on the pads. Can't think of anything else off hand without more information.

I would recommend using a scan tool that does ABS and pulling codes. ABS codes are stored in a diff computer than the PCM, so they will not set a CEL nor be visible when using a generic OBDII reader unless it specifies that it is ABS-ready. Definitely sounds like an ABS fault, either electrical or mechanical.
