i don't have much work with cars, however, electronically the circuit likely has a short. a pinched connection, or a stuck switch.
check the circuit switches for continuity.
I have attached a VERY BASIC Light Circuit. If the switch is closed, it gets current, if it is open, it does not.
Use a multimeter to measure Voltage drop from the switch, (Whichever one is triggered by the brake pedal to signal you are breaking)
If the multimeter reads 0V, then no voltage is dropped, and you have a short Circuit in the switch
Outside of that, your load circuits may be failing as well. i do not have the Circuit diagram for your specific car model, so i am unable to give you more that the simplest overview. i apologize that i can not help more
