Hang a incandescent test light ( or vehicle marker light ) on both sides of the brake light switch. One should be on while the car is running and the other when brake is pressed.
Drive around to test.
Is the switch properly adjusted? If the plunger does not extend enough you won't have brake lights. Just be be sure, is this a switch that mounts to the brake peddle or a brake booster mounted switch under the hood?
I know that BAS Brake Assist has a booster mounted switch but i have not researched this system.
