Question:

Hi my pop up camper did not come with electric brakes. I would like to add electric brakes and the wiring required for the brakes. Do you have any recommendations? Thank you

It looks like you've got a Dexter D35 axle, which will have a spindle that uses # L44649 and # L68149 bearings, however this axle does not have a brake mounting flange, which will be required to add brakes to your trailer. You will need to have this welded on by a certified welder with the appropriate jig to make sure that the flange is mounted square and concentric; I recommend using the Brake Mounting Flange for 2-3/8" Round Axle # 4-35 for this and you will need 2 of these for a single axle trailer.

Once you've got the brake mounting flange you'll need a hub and drum assembly, brakes, wiring and a 7 way plug. For the hub and drum, I recommend using the Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 5 on 4-1/2 - Pre-Greased # AKHD-545-35-K which use # L44649 and # L68149 bearings to match your spindles. For the brakes I recommend using the # AKEBRK-35-SA because they're self adjusting and you won't need to make constant adjustments to them over time to keep them working properly.

For the wiring, you'll need some 10 gauge wiring # 10-1-1, which is available by the foot; you may also need butt connectors # DW05745-10, ground screws # 101131802 and wire clips # CE16867A to keep everything organized and out of the way. To complete everything you'll also need a 7 way on your trailer; if you don't already have one I recommend using the Trailer Wiring Junction Box with 7-Way # HS381-9000 because it'll help give you a cleaner and easier installation.
