Question:

Hello, I want to install brakes on my 6x14 single axle continental cargo trailer. Do you know the kit I would need for that? It has the 3500 lb dexter axle. I would need to convert it to a 7 pin connector, and the correct wire for hooking it up as well. Bearings are L68149 inner L44649 outer 5 on 4-1/2 pattern Thanks

The brakes I suggest for your 3,500 pound axle are the self-adjusting # AKEBRK-35-SA assemblies. Since they're self-adjusting you need to do an adjustment when you install them but that's it.

The hub and drum assembly to match your bearings and bolt pattern is # AKHD-545-35-EZ-K. This includes new bearings, races, grease seal, grease cap, and lug nuts.

For the 7-way trailer connector I like # HS381-9000. It attaches to a junction box to make wiring everything easier. You'll also need ring terminals, # 44-5310A, to connect the wiring. Then use about 20 feet of 10 gauge wire # 10-1-1, which is sold by the foot, to run the wire from the junction box to the trailer's brakes.

The trailer will require a breakaway kit. The Hopkins Engager # 20099 is our most popular kit. The breakaway kit engages the trailer's brakes in the event the trailer is separated from your tow vehicle.

In order to control the trailer's brakes you must have an electric brake controller in your tow vehicle. I suggest the Prodigy P3 # 90195 because of how reliable and easy to use it is. Its one of our top brake controllers. If you tell me the year, make, and model of your tow vehicle I'll see if we have a custom harness to install the controller. And also anything else that may be necessary.

I've linked some videos on the products I've recommended for you to take a look at.
