If the "BRAKE" light is on then there is a problem with the sensor. I did some tests with the sensors when I was doing my brake pad change and found the BRAKE like would go out by itself after you start the car a few times with a good sensor installed.

The -9000 is indicating you are 9,000 miles past the life of the pads. I guess that value is displayed automatically when the pad wear sensor is bad.

The good thing is the sensors are easy to replace after you pull the wheel.
