Hello and welcome to the forums.
Yes they matter.
Yes the magnet contact area can be resurfaced if the grooves are not too deep. Most of the time it is less expensive to just replace the hub/drum assy and add a new set of bearings. It also sounds like you'll need new magnets. You are starting to get to a point where it may make more sense ($ and time) to replace the axles.
You can read a few axle threads here and get an idea what you are getting yourself into. You've come to the right place for assistance, for sure!

Thanks for the feedback.
Thanks for the welcome Top.

Trying to get the trailer towable since we are about four hours from where she currently resides.

I was considering complete axle, brake, drum bearing sest for her. But checking the trailer out this weekend, looks like the axles are in decent shape. They are not solidified and still have decent travel. Wheels look good. Tires and brakes are shot.

I figure about 2 years worth of renovations/upgrades, so I will probably replace the axles prior to any real travel plans since they are 30 yrs old. Just trying to get it home.

Looks like only one of the four drums is in real bad shape.
Question, if the grooved drum is unable to be turned, would you risk a one time/four hour drive just to get her home? (assuming new brake assemblies and tires)

Thumbs up Drive her home...

My experience with our 63 Safari....moderate grooving, 1/16" +- deep.

The brakes worked work fine, the worn magnet plate wore the magnet face to match. I just smoothed the surface with a die grinder as best I could.
In 15 seasons I changed the magnets 3 times when brakes serviced.

Thanks for all the feedback! Gotta love these forums and the experienced advice.

I figured I could get home with some grooving, but I've decided to quit pinching pennies on my first purchase. So new drums it is.
I found some drums locally, complete with new bearing kits. I am going to go ahead and buy them along with new backing plate assemblies and go get the old girl!

Looks the same, but if you are getting all new drums and backing plates, the brand you are replacing is irrelevant. The dimensions for 12"x2" drums are to an industry standard.

crabbey1-
Did you get it all back together and working? Any hangups?
Did your new backing plates come with spline studs? or did you cleanup and reuse the old ones, or maybe just new bolt/nut combos would be fine.
Sorry for the bombardment of ??s....

looks like the magnet in new assembly is larger than older one.. also anyone spray painting the new drum with high temp paint to control rust ??

I found these new brake assemblies for what seem like a good price here.
Utility Trailers, Enclosed Trailers, Shivers Trailers | Agri Supply

they are local to me which is nice..

Just a retired knuckle buster commenting here....

They may be the best thing since Thor took over Airstream, but I'm a bit skeptical of $49 brake shoes. How they can supply the whole 9yds for that price is a wonderment....China is a long ways away.

Dexter replaced my brake shoes under warranty recently, they didn't require a core return.
It will cost me $80 to have them re-lined locally, I'm much more comfortable with that option.

For some the 49 dollar route is very appealing because of the ease of accomplishment....understandable.
Do do your own research & rationalization and decide.....

I wouldn't worry about a bit of rust on the outside, it's the friction surface's inside thats important.

I went by and took a look myself and they do say made in china..
they do look like the ones in the pictures so not sure the difference. the brakes are bonded not riveted on.

picked up a 12" hub with 8 bolts and man that thing is HEAVY...

so what is the pricing on the dexter backing plate kits with all the stuff shown.. vs the ones made in china..

Dexter I am sure is made in China as well. If you are looking for American made parts you won't find them.

So now that I have installed the new brakes, is there a way to test them other than hitting the road?
