NO Brake Lights or Turn Signals
Because neither brake light nor turn signals work, it is unlikely that it's due to burnout of all of the bulb filaments at the same time.
Without doing a "hands on troubleshooting" of the circuits involved no one can tell you what specific defect is causing the problem.
However, here are some of the possible causes you need to check for:
- The fuses for those circuits have "blown."
- Brake light switch mounting is not properly adjusted.
- A connector plug somewhere in the circuit (s) has become "unplugged," or loose.
- A conductor [wire] somewhere in the circuit has been cut, broken, "pinched," or pulled apart.
- Corrosion has occurred inside any one or more of the connector plugs, or at any connection/splice/ground, in the circuit. Corrosion can "block" the flow of electrical current just the same as if a wire were cut.
- The brake light and turn signal switches have become defective [this is usually the "last" thing to fail, and in this case very highly unlikely].
There are probably a few more that I can't think of now. Good luck!

Why are your brake lights and hazard lights not working on a 99 Chevy turn signals and top brake light is working fine?
turn signal switch needs replaced!
My 87 Honda accord brake hazards and signal lights stopped working I changed signal and brake light fuses the brakes lights are working but not signal and hazards.?
Probably the flasher unit needs to be replaced. This is an electronic switch which usually mounts underneath the dashboard.
Will a bad signal light flasher stop the brake lights from working on a 1983 dodge d 150 pick up?
Assuming the signal lights still work, no. But a bad brake light switch or a blown brake light fuse could.
What causes the tail lights not to work on a 1995 Chevy Tahoe when the turn signal and brake lights do work?
either dimmer switch or blown fuse If you are saying that the tail brake lights are working but the third brake light is not....It may be a defective turn signal switch in the steering column.
Why are the brake lights on a 96 ElDorado not working if the fuses and bulbs are good but the hazard lights are bad?
It needs checked out but both the hazard and brake lights go through the turn signal switch.
What could cause the brake lights to stop working on a 1992 Camaro RS if the bulbs and fuse check out ok?
If the turn signal is working it's either the brake light switch or the turn signal switch.
When my running lights are working on my trailer my turn signal lights and brake lights don't work but if running lights are off turn signal and brake lights work?
I would check the running lights for one with a short. I had the same sort of thing with my trailer and I spent way to much time troubleshooting the brake and signal wires. Turns out a running light bulb connector was grounding out on the trailer and messing it all up.
Why would the brake signal and hazard lights stop working simultaneously in a caprice?
Bad bulbs? Sockets corroded?
98 Tahoe no brake lights changed the brake switch still no brake lights and now the hazered lights not working at a lost on what to do?
If the fuses and bulbs are okay I would blame the signal switch assembly. They call it a multi-function switch these days.
Third brake light works but no other brake lights working on 92 eldorado what could it be?
blubs blown? Check the turn signal switch.
1997 Cadillac eldorado has no brake lights the brake light in the rear window works and all signal lights work just no rear brake lights?
the turn signal switch is probably bad
What is wrong when brake and signal lights work but tail lights do not?
Fuse
