Brake lights and turn signal switch

I had the same problem...your probably not getting power through one of your brake switch wires...the one that doesn't is ran through the turn signal switch...if your turn signal switch is bad then the wire on ur brake witch won't get power...I think its a red and one white wire...my white wire wasn't getting electrical current.

hope you fix it! I scared a lot of people on the sttreet when I stopped and had no lights haha
