On this page (typically below the product links) there is a helpful link section that will have the install instructions fo the Hopkins Breakaway kit part # 20400 that you referenced. I also attached an install video that shows the kit installed as well as a diagram for trailer breakaway wiring as well. The white wire is the ground wire.

If you wanted to upgrade to 12" brakes you would also need to replace the existing hub assemblies with corresponding 12" units. You might be able to do this depending on what spindle type you have on the trailer. If you can tell me your axle capacity or the inner and outer bearing numbers that are used on your current hubs I will be happy to recommend the right parts, if available.

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.

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…

When selecting the correct replacement axle for a utility trailer you will need to know both the hub face (wheel center) and spring center measurements. For example, if your current hub face measurement is 88" and you replace this with an axle…

Typically when this happens without a trailer being connected, it's because of dirt or corrosion in your trailer connector. Take a look at the pins on the 7-way connector. If you see any green or white corrosion on the blades, use a piece of sand…

Domestic trailers have a 2-wire system where there is a circuit for the running lights and a circuit for the brake lights and turn signals; our trailer connectors are not configured for a separate brake circuit. You can separate those by using…

If the spring seat dimension on the axle does not match up the suspension won't work properly as it will be bound up instead of able to move freely. This also would cause premature failure of the components as well so I'd have to recommend…

Answer 10

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…
