It is damn sparse out there for troubleshooting a trailer. Its a 2015 tandem axle with trailer brakes to both axles. Only front left tire brakes with truck. None of these others work even with gain and sensitivity at full on. So we know im getting power from the truck to the back. Connectors like new and not corroded with dielectric grease to help. Now I pull the brake-away switch and I can get 3 of 4 wheels to grab. Plug key back in and now Im down to only one tire braking on each side. I looked in behind and all four have the like new 3/16" of brake pad left.
Ideas? How can I go from 3 of 4 working to only 2 of 4?
Magnets siezed? Other ideas? TIA
