Have you checked the fuses or bulbs?
Wal mart, any auto store. They are everywhere.
The brake light is controlled by a relay switch. If the relay switch is bad the brake lights will stay on. The brake light switch simply plugs in and out. Unplug the brake light switch until you can replace it.

its an LED light, the whole unit has to be replaced. The spoiler needs to come off.
Check the brake light bulbs, one of them may not be installed correctly.
mine is a button on middle council, by emergency brake. says ect
Brake fluid is low.
I would suspect low fluid level. If the fluid level is ok, then have the brake system inspected.
I just did this on my 4-runner and took pictures. Check out my web sight and see if it helps you. http://www.95zuk.com/tail_lights/
If you have the same bulb for brake and signal, brake light power needs to be interrupted by the signal lights, The brake circuit has to go through the signal light switch so the problem could be there.
the brake light wiring often runs through the turn signal switch i would test power going in to the brake light switch on the pedal and power coming out when pedal is depressed if power is ok suspect turn signal or hazard switch
Check the signal light fuse, the signal light relay, and the signal light switcher.
