How do you fix brake lights?

First you need to determine the cause. It could be blown bulbs, blown fuse, out of adjustment brake light switch, bad brake light switch, damaged wiring, loose or bad grounds, etc.
Most times, when your break lights are not working the bulbs need to be changed. You need to change the bulbs through the opening in the back of your trunk.
