When the brake lights will not come on, the first thing to check is the third-brake light. If it too is not working, the brake-light switch, a bad fuse or an unplugged harness is likely. The emergency flashers often use the same wiring, bulbs and sockets as the brakes.
Why do my tail lights work but not my brake lights?
One of the main reasons why you might see your brake lights working while your tail lights don’t is because the bulbs installed in the tail light were faulty.

If none of the brake lights are working, we are going to follow the circuit from the fuse box back to the brake pedal. At some point the power is not getting from point A to point B. We just have to find where that is. Please note that tail lights can work even if the brake lights are burned out.

Why does my brake light not flash when I Turn on the turn signal?
On this type system, the turn signals and brakes use the same circuit. When we use the turn signal switch, it cancels the brake light signal, on the side selected. If it did not, the lights would stay on and not flash. A bad turn-signal switch may interrupt the brake light circuit when it should not.
