Trailer brake problem, please help!!!

I friggin hate trailer brakes!!! ok here is my issue. First off I dont have a ohm/voltmeter here so that isnt helping. However, I do have a +12v test light which shows power coming through the trucks trailer plug, power going to each brake, and can hear the brakes humming when I hit the brake or slide the manual brake on the controller. When I use the slide on the controller the +12v light does get brighter but brakes wont engage.

I have adjusted the brakes several times and I'm pretty sure thats not the issue. Just to be positive I tightened them all the way down and the still wont engage with the truck.

What am I missing?

How is the ground point for the brakes themselves? Check them for corrosion.

Cleaned them, still no luck.


The drum does have some grooving where the magnet grabs the drum? Wonder if that would cause issues?

I wonder how much wear may be on the magnets inside the drum , The magnets do wear out

This is normally the case along with glazed drums. With age the magnets get weak. I just re-did one of my many trailers and took the cheap way out and did not replace or cut the drums after replacing all the backing plates. They grab but wont stop. I am about to break it all down again and cut the drums.
