if the tail lights work but not brake lights then its most likely just a blown fuse or it could be the switch at the top of your brake pedal arm.
the connection between the battery and the brake lights
I always start with the basics.......fuses. Then go to bulbs...... Look in your fuse panel and see if you have one marked tail lights......and check it. the brake, headlights and signals work off another circuit.
check the brake light relay under the hood
It has a flasher relay for the signals only.
the circuit boards on the taillights are bad.
i have tail lights but do not have brake lights nor do i have turn signals. i have replaced brake switch and all bulbs
Its the steering colum
A bad brake light switch, and it is bolted to the steering column in under the dash.
turn signal switch needs replaced!

If the vehicle is equipped with a trailer light plug, the wires for the brake lights and the turn signals have been connected together, which is common, as many trailers do not have separate lights for brakes and turn signals.
