Really the only way to tell if you have manual or self-adjusting brakes is to remove the hub and take a look inside. If you can see a cable running at an angle (see included photo), then you have self adjusting brakes like the Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-35-SA.

If you do not have that cable, then you have manual adjusting brakes like the Electric Trailer Brake Kit # AKEBRK-35

Answer 6

The biggest difference between Dexter brake assembly #23-459 and etrailer/AxleTek assembly #AKEBRK-7L-SA is the pad material. The Dexter assemblies use pads that are snapped off of a long strand of the material. The ones on the etrailer assemblies…

There are a few things that could cause one side of your brakes to drag after adjusting. This could be either a broken spring, faulty adjuster screw, or possibly a pinched wire on that side but you would hear the magnets buzzing if this was the case.…

Answer 8

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…

Answer 9

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…

Answer 11

I was able to find the 126003 hub and was able to determine that it is a 3,500 lb hub/drum with a 5 on 4-1/2 inch bolt pattern just like the #AKHD-545-35-K that you referenced. This hub will work as a replacement for your Lippert.
