So lets start simple. There is an adjustment for the brake light switch. Did you make sure that the switch is fully depressed when the pedal is fully released? If not, screw it in to the mount until the switch is full depressed. If so, you could have the wrong switch. sometimes they get packaged improperly. Take a multi-meter and put it in "Buzz Mode. Pull the plug off the switch. Put you leads on the switch contacts and see if it buzzes. If it does, you have the wrong or a defective one.

This switch doesn't have an adjustment it just slips in the pedal rod and clips on the power booster rod
