If I recall the brake switch is hooked into the PCM to turn off cruise control. You can hook up to a scanner to see the brake switch go on and off. The cheapest "try or guess" would be to replace the switch. Your proble could be more complicated such as a bad connection fro the switch to the PCM. Your brake lights would still come on but cruise control would not get a signal.
