Most trailer's are wired up so that the turn signals and the brake lights are carried on the same circuit. So what you are experiencing is normal, but there is a way to do what you are trying to accomplish.

You will need to use a signal converter like # C56196. When you wire this to the trailer wiring you will get the stop light circuits separated from the turn signals.

I attached a diagram that shows how it will install.
