I understand the overall concept of how electric drum brakes work. Magnet, drum, actuating arm, shoes move out against the drum. Pretty simple.

But why is it when people talk about doing brakes on their trailer, what they mean is replacing everything outboard of the spindles? Is it really not worth the effort? Figuring in the time it takes to install new shoes, replace an old magnet, etc, you could just unbolt the backing plate and slap on a new one?

What about the drums? Seems like they could be resurfaced. Repack the bearings and stuff a new seal in the back... should be good as new.
 
The problem is getting the right parts. For some people it's too difficult to search out and they just replace is all.

Example: "everything" for my axle @ redneck trailer supply is approx $40 per side. The only thing that does not include is the drum. Just the shoes is probably half that cost and I still have to tear everything apart.

Yeah, that's kinda what I figured.... but at $6-700 for everything, I'm still on the fence a little bit about replacing all of it. Definitely makes it easier, and no screwing around w/sending the drums off to get turned, etc.

Tell me more. Where is redneck trailer supply? Is that just a 3500# axle?

I'd need auto-adjusting 12x2" for a 7k Dexter EZ Lube. Looks like $80 for a loaded backing plate and $85 for a loaded hub/drum from etrailer. Agrisupply is a bit cheaper, but I dunno who makes their stuff.

Yes...3500 lb axles.

Redneck Trailer supply is Lincolnton, NC. Give them a call. $85 for 7000 lb loaded doesn't sound bad though.
