Question:
I’m trying to find out what trailer brake assembly I need for 5.2k to 7k axle 3 inch diameter, and the mounting flange bolts measure 3 1/4 by 2 3/4. Uses a 12 inch drum

Expert Reply:
Most trailer brakes for 5.2K to 7K axles are going to use a 5 Bolt Flange # 4-44-1 like that which is found on the etrailer Brake Kit # AKEBRK-7-SA. We do have the Dexter Brakes # 23-105-106-09 which also has a 4 bolt flange but the dimensions are slightly different than what you mentioned. These bolts are not a perfect square with the lower holes spread 2-1/2" on center, upper holes spread 3-1/8" on center and the holes vertically spread 3-3/8" on center.
The 5 bolt flange also does not have an equal spread so I have included an image with these hole dimensions.

Thank you for that info, but that is the jist of what I’m looking for, a 4 bolt square pattern that measures 3 1/4 inches by 2 3/4inches on the brake assembly to mount on the axle. I could try just repairing the old current ones I have but I’d need maybe a new magnet, an adjuster, new shoes, and maybe new springs, not sure. How I upload a photo to this message board to show you please?
