For 3,500 lb axles you will use 10 inch assemblies. My recommendation is the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA for each axle. These assemblies will work well for your axles and are self adjusting. If you don't already have the hub/drum assemblies, then I recommend using the Trailer Hub and Drum Assembly - 3.5K E-Z Lube Axles - 10" Diameter - 5 on 4-1/2 - Pre-Greased # AKHD-545-35-EZ-K.

Nine times out of ten the issue is that the brakes on the trailer will need to be adjusted. What likely has happened is that trailer brakes have worn down enough but have not been adjusted out to compensate for the wear. This means that you would…

You might have one brake that's adjusted tighter than the other. That's really the only thing I can think of that would cause one hub to get hotter than the others when brakes are applied. You want your brake controller to be set so that it…

Self-adjusting brake assemblies are the way to go like with the #AKEBRK-7-SA which do fit your 7k Dexter axles. The only real reason to go with manual adjust is really just cost. At one point the self adjusting models were much more expensive but now…

Answer 9

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…

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…

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…
