If you look closely at photo you will see a pretty good bend where the brakes attach. What's the best way to straighten this? THANKSbend

I'm sure those don't bend that easy. Wonder how it got that way in the first place.

I'd also like to know how they get bent up like that.
Most of the axles in my collection have been used in trailer service and it's flippin amazing how beat up some of them get!
I'm with Charley at this point. Adjust it back into place with a hammer.

Charley and Duey are absolutely right. I was afraid it'd crack one if I took a heavy hammer to it, but I found it will bend and not break. Corrected quite a few that way. I suspect the backing plates are made of cast steel. Others will know about that.

Actually, it's not steel or cast iron but malleable iron. It can take a lot of stress before cracking.

Looks like maybe the rear seat was overloaded.

I would use a big crescent wrench. Much more controlable. No need for an anvil and the chance of mis-hits.

I've been able to straighten them with a large monkey wrench. They bend easily.

Interesting. I rebuilt the rear axle on my '23 this winter and when I installed the wheel I noticed that the distance between the brake drum and backing plate is slightly greater on one side ... maybe a 1/16"

I rotated the new axle in the housing before installing the bearing and it was centered. Adjusted the radius rods. Everything else is ok ... so now I'm wondering backing plate is simply a little out of whack. I do remember having one housing side roll off a table one day when I was cleaning it. Should I give it a few careful whacks with a lead hammer.

Mark - if the distance between drum and backing plate is even all around, the backing plate should be OK - the difference in distance from side to side might be due to a worn hub (can be shimmed if too tight and grinding the brake shoes) or due to the shimming inside the differential.

Some repro axles are made slightly longer to compensate for extra Rocky Mountain drums, worn hubs etc.

Here is what it looks like. There is no binding of the axle and it sits in the center of the housing with the bearing removed. Not sure if this is a problem that I shouldn't worry about ... or address it.

Ok, slightly bent if the camera lens hasn't distorted the view. Maybe not much to worry about if the emergency brake shoes works as they should?
