Turn Signal / Brake Light Troubleshooting (check in this order):

2. Check Bulbs
3. Check Flasher Relay

Most likely its the fuse or bulb. See sources and related links below for bulb information.

How do you replace brake lights
You may have blown a fuse. Check your fuses. Then you can check your light connections.
It depends on the vehicle but in general you would have one fuse for the signals and one fuse for the brake lights.
Brake lights
Fuse 7 controls the brake lights. It should be a red 10amp fuse.
Blown fuse
Brake lights and turn signals are on a separate circuit from the tail lights. Tail lights are on the same circuit with the dashboard lights. If the dashboard lights aren't working either, check the fuse. If they ARE working, check the headlight switch.
Could be the brake light switch or fuse.
i have tail lights but do not have brake lights nor do i have turn signals. i have replaced brake switch and all bulbs
It is not necessarily the fuse. It could be the switch on the brake that is not closing the circuit.
