My boat trailer has brakes that lock up nearly everytime I back up. After jacking with them and jammin the truck back n forth a few times they release and work properly. I am at my witts end. Can I just disable these things? I dont think they help me stop, never felt any help instopping, but this reverse thing is about to drive me crazy. Especially when you get to the ramp, with others there, and you try to back down the ramp but cant cause the brakes locked. HELP PLEASE
