You need to be sure you are getting power to the brake switch. The other aspect is that the brake switch is before the turn signal switch in the circuit, so on occasion the turn signal can actually cause the brake lights to not work. You simply will have to keep checking the circuit until you get to where there is power. Once you find power, you can determine where it is being cut off. The brake switch should always have power to it.
