Hey Matthew! You can email me those pictures at the address you receive this response from but what I really need to know is the size of your current brake assembly and the mounting pattern of the bolts that attach it to the flange on your axle. Specifically the diameter and width of the brake assemblies.
The etrailer Electric Trailer Brakes item # AKEBRK-7-SA you were looking at fit a 5 bolt mounting flange and measure 12" diameter x 2" wide. These work with wheel sizes 14-1/2", 15", 16", and 16-1/2" and axles with 5,200 lbs, 6,000 lbs, and 7,000 lbs capacities.

Hey Matthew, were you able to measure the diameter and width of your trailer’s brake assemblies? Once you have those details, I can help confirm if the 12" self-adjusting brakes are the right fit. Let me know what you find—I’m here if you need a hand narrowing it down.
