Definitely off topic. Had to replace one axle on a duel axle trailer. When we got the assembly the axle was mounted on the bottom of the spring. It needed to be on top to match the other. We removed the axle, spun it 180 degrees and mounted it to the top of the spring. The brakes are now 180 degrees out. It looks like they will work correctly but upside down. Will there be a problem with this. I'm sure that we could reassemble the backing plate & shoes to be in the proper position without much trouble if needed. If there is going to be a possible problem I would rather spend the time and change them.

???? Is this a new or used trailer, or something you've had for a while, and have now decided to do something about an issue that was't right??? Removed and spun it around 180 degrees, and now the brakes are "upside down"??? Drum brakes have a smaller primary shoe that always goes to/facing the "front" of the axle; the rear or secondary shoe is a little larger than the primary show, and is to the "rear"; like this orientatioin, Primary shoe: ( Secondary shoe: ). Why was the axle spun around 180 degrees? An issue with the spring pad mounting on top of or below the axle? Hydraulic or electric brakes? You should be able to redo how the shoes are installed, and be fine. Unless I'm missing something here. I've been rebuilding a car trailer myself, and had to completely rebuild the electric brakes.

This is a used toy hauler that my son has had for about 10 month. Last trip out one side axle froze up, distroyed the bearings and just about fell off. The replacement axle was from the same co. that the damaged axle was from. There was no indication as to front or rear on the axle so it could have been installed with either side facing towards the front. I know that car/truck brakes have a front & rear shoe but did not know if the trailer had the same and could find nothing on Google or Youtube to indicate if they were infact the same or different. The only thing that I found out is that on the one video that I saw it was very easy to remove the backing plate and put it back to the correct spot. The 4 bolts were not hidden behind any brake parts like in a car and the complete assembly could be removed and turned as one unit. I do not know if ours is the same because we did not have time to look due to disappearing sun light. These are electric brakes In rethinking this if we had spun the axle so that the mounting pad was at the 6 oclock spot as needed ( this we did) but if we had also spun the axle putting the now left side on the right side then the brake shoes would be correct but still upside down. Our other problem was that we had someone (a mechanic) helping that was working way faster than I could think or analyze the problem. correctly. Any further information will be helpfull

If it was mine
I would be pulling all hubs,regreasing every bearing and adjusting them
Last trailer I bought had 2 out of 4 set to loose, almost no grease on the bearing and only 3 drums adjusted proper
And this was a brand new trailer

Change the brakes to the correct leading and trailing. They may have bolted them on wrong from the factory.
