Hi everyone. How do you tell if surge brakes are working? I have a 23' Imperial WAC boat on a tandem axle trailer with surge brakes that I pull with a F250 Diesel. It doesn't really feel as though the brakes on the trailer are working. I really have to apply pressure to the brake pedal when stopping. The trailer was bought new a little over a year ago. I also have a 27' travel trailer that I pull that has electric brakes, and I can tell a big difference in the way it stops. Is there an adjustment on the surge brakes at the tongue, or at the hubs that I could take a look at? Any and all help appreciated!
