what sized wiring for brakes?

I am replacing all the wiring on a 58 jewel, I know the running, and brakes lights will be run in 14 guage, I am just wondering what size should I run the electric brakes in. I think 14g is a little on the light side and as you all know wire isnt cheap so I want to make sure I get it right the first time.

!2 stranded should be adequate. Standard practice is to run both leads to the brakes, hot and ground instead of picking up ground from the trailer frame.

Yes #12 is the min. Another consideration is the size in the TV. I run a separate # 10 wire from the brake controller to the rear of the TV. Voltage loss over the length of the wire is the reason. Many manufactures use #14 wire in the factory wiring and this is inadequate.

Thanks, I am thinking seperate dual #10 from the harness connection to each brake.
