Brakes, dilemma.
I just had to have all new brakes put on my trailer at about 13K miles. 3 of the 4 were metal to metal. Usually run the controller 5/6. Has anyone heard of a brake test using a compass? It says with t...

Lol, then just say its not a good test. Done. Personally, its the first time I ever heard of using a compass, pull the wheel and test the magnet with a metal tool, yes. Meter yes. I have had my share of weird brak problems. So sometimes the fix is evident, sometimes its not. I did learn, that with the harder stuff , its easier to rewire then to troubleshoot.
The most likely problem with e-brakes will be magnet not getting power. And used right, a compass will tell you this magnet is not working with no teardown, or even getting under the trailer. This is why LEOs will use it roadside on CMVs (in theory, a fish hook on a short line could work)
My problem with the "easier to re-wire" crowd is it is also easier to just leave the old wires there. And because they could not find a problem, likely the rewire job will have problems shortly. So they rewire again. Then when somebody does try to troubleshoot, bunch of extra wires to sort out.
Off topic but kinda funny. I decided to take Bobcat out to work with my '54 F5. No CB, so I was surprised by a roadside safety inspection. I watched the mirror, pumped the pedal while the kid in uniform waved his compass around the trailer wheels. He gets my Out Of Service paper all marked up, hands it to me to sign. "What makes you think my trailer brakes don't work?" loud for the senior inspector to hear. Senior, who had been inspecting my stuff for years, looked at the tongue of trailer, "Surge brakes are PITA. Scooby, do they work?" I asked if he wanted me to pull break-away. "Naw, we'll just mark this 1 as training."
