bad bulbs, bad fuse, or brake light switch on the metal arm of your brake pedal under your dash.
brake switch ???
fuse, bulbs
Most likely no brake lights would be due to a faulty switch on the brake pedal or a bad fuse.

Blown fuse or bad brake light switch?
brake light switch would be most common cause
check the fuse for the brake lights, they have thier own. also check the brake light switch at the at the top of the brake petal
The BOO (Brake On/Off) Switch may need to be replaced. If it is bad, it would cause the brake lights to NOT illuminate when the brake pedal is applied.
BAD BRAKE LIGHT SWITCH AT TOP OF BRAKE PEDAL
Possible ground issue at the taillights.
The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.
Those tail lights could be the brake lights you are seeing and that would be a faulty brake light switch or the brake light switch is out of adjustment.
