I have a Toyota Corolla 2003 and break lights don't work. I've checked fuses and...

First try putting on the 4-way flashers, - if all the turn signals work, you know all these circuits work! Now some of these have separate TS and brakelight circuits, - some run through the TS switch! So of course you have to see which you have!
I think it is not hard to get to inside of trunk and get to lights, -- you can pull bulb an look at it, - and it is possible that it has same kind of bulb in another socket! If so you can swap and see if they work the same as before, or problem now switches- if it switches it is the bulb!
Now there is a switch down under the dash that brake pedal arm hits on when you do not have your foot on pedal, if this switch is broken, stuck, or unplugged the brake lights will not work!
If these things all check good, then you have socket grounding problems possibly, - and if they use same bulb for brake and ts both, then possibly the blinker switch is bad!
By the way the bulbs are not that expensive, - buy one and try swap outs, - if that is not problem, - it is nice to have a spare bulb in glovebox anyway! I always carry one headlight bulb, and one of each of the outside bulbs, - since I figure it is better to change bulb than being in an accident!

They can be just burned out. If you have a rear window brake light and it also is not working, look for brake light fuse burnout.
If it appears the bulbs are burned, they are most probably the same bulbs as the tail lights, but a separate filament. Looking in the bulb, the heavier of the 2 filaments you see is the brake light filament. It could look alright, but flicking the side of the bulb with a fingernail may reveal that 1 end is no longer connected. Replace the bulb.

You may have a bad brake switch. The brake switch is activated when you press down on the brake pedal. When the switch is pressed by the pedal, it sends electrical current to the brake lights. The switch should be located near the top of the brake pedal metal, that goes up under the dash. Hope that helps.
