Electric Trailer Brakes for 4-Bolt Flange 2-5/8" x 3-5/8" Apart


I have a homemade gooseneck. The backing plates are a 4 hole pattern but they measure 2 5/8inch side to side and 3 5/8inch top to bottom. The outside diameter of the drum is about 13inch in diameter and 2 1/2inch deep. A local trailer shop couldnt find anything do you have any options for this. If not will be getting new flanges to weld on and go the standard 5 hole route.

I do have an option for you but none of our trailer brake assemblies are designed for this brake mounting flange pattern. Therefore, I recommend new flanges which will need welded to the axle; part # 4-34 for 1-3/4"axles, part # 4-35 for 2-3/8" axles, and part # DM52415 for 3" axles.
