Correct Hub And Drum For 3,500lb Axle Electric Trailer Brake

Question:

I am looking at your part AKEBRK-35-SA as a first time installation on an older 3500 lb axle with the 4 bolt flange. I want to know what is the correct hub/drum part that I will need to go with these brakes?

To make sure you get the correct fit, we need to match up a few characteristics first.

We know you need the weight rating to match your axle capacity of 3,500lbs. We still need to know the bearing sizes so they are the same bearings as the original to ensure spindle fit. Finally we need to know what wheel bolt pattern you have to match up to your original so that your wheels/tires will go on as usual.

The 5-on-4-1/2 bolt pattern is the most common in RVs, one like 10-inch hub # AKHD-545-35-EZ-K which works on an EZ-Lube spindle with a grease fitting. The linked diagram shows the usual appearance of bearing part numbers.

I've included the hub/drum page where you can click on your bolt pattern, then on the axle weight capacity and then on the inner and outer bearing part numbers in your existing hub. Also select your wheel size. You will then see the hub/drums that are compatible. Out kits include the hub, bearings, races, seal and even lug nuts and grease cap.
