if your not sure which fuse works the brake lights, check them all.but its more likely to be the brake light switch situated above the brake pedal, it is actuated by the brake pedal itself, sometimes they work loose or just pack up. once youve found the switch, if you have the ignition on link out the two wires, this should put the lights on, if they come on, then the switch is faulty.hope this helps
