More than likely this is a stop lamp switch. However, we can test this by jumping the switch and find out if the brake lights come on.

If they do not, then we may have an issue with the multi-function switch as this power is sent to the switch.

Another way to find this is to check the voltage coming out of the switch when you are pressing the brakes. If you don't have any the switch, is the issue.

I am attaching the info on this system and the switch so that you can check all this.

Please run through this info and let us know if you have other questions.
