Options for Adding Electric Brakes to Trailer Axle without Brake Mounting Flanges
Updated 04/04/2025 | Published 11/05/2019
Question:
My trailer has no flange to mount a brake system. How do I find the correct place to weld the flange? P.S. This is a small trailer pulled by a motorcycle about 500 LB. loaded if that.

If your trailer axle doesn't currently have brake mounting flanges you have a couple of options, one of which is to simply weld on flanges like you mentioned. A brake mounting flange needs to be welded perfectly square and concentric, which typically requires a special jig and a certified fabricator with experience in this type of application. This isn't a DIY project, as it's vital that it's done with precision so you don't have suspension issues on the trailer down the line.
Finding the right tools (and people) to properly weld on new flanges can be difficult and potentially expensive, which is why a lot of people tend to simply replace the whole axle altogether with one that already includes mounting flanges. This is your second option and is honestly what I recommend.
If you can tell me the capacity and length of your existing axle I will be happy to make a specific recommendation. I have also attached a couple of links that will take you to our complete axle and mounting flange selections, depending on which route you choose to take.
Lastly I have added a great article below that details all the components needed to add electric brakes to a trailer that you might find helpful.
