If you are looking to replace the existing electric brake assemblies on your trailer, you will just want to note a couple of things. First, you will need to measure both the inner diameter and depth of your hub/drums. I have attached an image that clarifies the dimensions you need.

Then, you will want to make sure that the brake assemblies you choose match up to the bolt pattern on your axle mounting flange. Finally, the replacement assemblies should have the same weight rating as the axles on your trailer.

For example, the etrailer.com Electric Trailer Brake Kit # AKEBRK-35-SA is designed for 3,500 pound axles and includes two 10 inch x 2-1/4 inch electric brake assemblies. They feature a 4 bolt mounting flange pattern.

If you can tell me the above information, I will be happy to recommend a specific kit. If you are actually wanting to install brakes on a trailer that does not currently have any, please let me know and we can dig into this a bit further.
