How to Determine Correct Hub & Drum Assembly For 7,000 lb Axle
Question:
trailer brakes. I have B12EA-22 can you tell me which drums I need. Thanks

Expert Reply:
The brakes you mentioned are for 7,000 lb axles and are 12-inch assemblies, similar to the Dexter Electric Trailer Brake Kit # 23-180-181, but that is just one part of the equation in regard to determining the correct hub and drum. In order to determine the correct hub and drum for your 7k axle(s) you will need to know what bearings and grease seal you have.
You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use digital caliper and measure your spindle to the thousandths of an inch where the bearings and grease seal ride.
The most likely is the Dexter Trailer Hub and Drum Assembly # 42866UC3.
This hub uses inner bearing 25580 (1.75" inner diameter), outer bearing 14125A (1.25" inner diameter), with a grease seal that has a 2.25" inner diameter. If that isn't the correct option for you I have added a link below to our entire selection of 7k-rated hubs, or if you let me know what bearings and seal you have I can point you in the right direction.
