Good afternoon

The diagram I attached will show the wires from the brake light switch to the rear lights.

I would inspect the wiring from the switch to the rear of the car. Check for power at the rear sockets with the pedal pushed. If you have power, it could be either the socket, bulb or ground wire.

If you have no power, then you need to trace the wiring.
