Question about trailer brakes
My brake coils on a Dexter 3500 pound axle are not wearing flat. There is a ridge at the bottom of the coil as if that portion of the coil is beyond the armature on the hub and isn't seeing the wear ...

Ballpark mileage on those brakes?
For that wear on the magnets, the drum must have a groove in it. If everything works and the drum groove isn't too deep, I'd just use it as is. Other wise, if you replace the magnet, you need to replace the drum or the new magnet will wear the same as the old one.
Those brakes have got close to 24,000 miles on them. This will be the third time that I've cleaned and repacked the wheel bearings and also cleaned, lubed, and adjusted the brakes.
I bought the trailer new and each time I've worked on the brakes, I've seen that ridge. Last year I got a little ambitious and filed the ridge off. The brakes for the most part work fine. If I have the amperage turned up too much, I do get some surging.
Your comment about a groove on the hub (actually the armature) is interesting. I was in a hurry today to take things apart, take pictures, and then put it all back together. I didn't spend as much time as I should have inspecting the parts. I do think I see in the picture a groove near the outer circumference of the armature. That groove is much wider than the ridge on the magnet though. I don't know how deep it is.
