There are brake assemblies that are compatible with 10 inch trailer wheels. 7 inch hub/drums will fit behind a 10 inch wheel. I attached a link to a page that has all of them listed.

You will need to first determine what spindle you have on your trailer so that you can pick out the correct hubs. You can do this by the bearing numbers or with the spindle dimensions. I attached a picture that shows where to measure.

Answer 1

I went out to the warehouse and grabbed a 7-Way Molded Trailer Wire Connector #H20046 to measure it for you. I used a set of digital calipers to get an accurate measurement. The diameter of the outer black sheath is 0.59 inches or 19/32 of an inch. A…

With the right size hub and drum assembly you could technically use 7 inch brakes on anything. The problem is that 7 inch brakes are rated too low for a 3500 pound axle. They are only rated up to 2500 pounds. The other issue is that the hub/drums…

You would need to step up to a 3500 pound set up to get an axle that comes with brake mounting flanges. You could have brake mounting flanges welded to a 2K axle if you wanted but it is a precision job that requires the proper equipment and someone…

I will have another option available, but with the widths you got, you have an inner bearing #L44643 and an outer bearing #LM11949. The length of your spindle is also going to mean you have one that is shorter than standard and we will not have a…

Good afternoon! I am not sure what the stamped numbers mean but 3" diameter axles will typically have between 5,200 lbs to 7,000 lbs capacity. As far as replacement parts for it, like hubs, you're going to need to pull one of your hubs off…

There are usually identifying marks and other information on the outside of a trailer brake drum that indicates what it is. But if you go by the inner width and diameter and select the correct bolt pattern to match what you have then the part number…

We do have the Dexter Trailer Hub and Drum Assembly for Standard #8-271-7UC3 or EZ Lube #8-271-7UC3-EZ axles. These are the 8-271 hubs you have with the 5 on 4-1/2" bolt pattern. These fit on a 1-1/16" diameter BTR spindle. They include all…

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…

The load range tire used is going to depend on the gross trailer weight capacity, which should be on a sticker or plate near the front of the trailer frame or in the trailer's literature. It probably also indicates the load range, or at least the…

Although I can't speak to why someone printed that on a tire, but the two sizes are almost exactly the same, so maybe it was an approximation by the tire manufacturers. Essentially you can swap the two out with no issue because a 20.5 x 8 -10 is…

Answer 11

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…

Answer 12

For Dexter hub/drums that are 10 inch diameter like the #AKHD-545-35-EZ-K the smallest wheel diameter you can go with is 13 inch like the #AM31994 which is a tire size of 175/80R13 mounted on a wheel with a 5 on 4-1/2 inch bolt pattern.
