Problem With Trailer Brakes

I recently bought a new 20' GN Lowboy trailer with brakes on one axle. My truck is the only truck I have been able to pull it with. I can turn my gain all the way up to 10 and activate my trailer brake fully and it does slow down a little, but I figured it should lock them up at 10 and it being empty? I don't know anything about the brakes on the trailer, but do you guys think it's the trailer or something in my controller? Like I said the trailer is brand new...but so is this truck.

The trailer brake control module in your truck is designed to NOT lock up the brakes on the trailer.

You might need to jack up and pull the wheels/drums to check the shoes and magnets. Trailer brakes can be adjusted similarly to the old automotive drum brakes. They may be out of adjustment.

I don't know a whole lot about GN trailers, but only having brakes one on axle seems weird. Doesn't seem like that's enough braking.

While it is true controllers aren't designed to lock up the brakes, when you manually operate the controller you should feel a good pull.
