Replacing Brakes on Northwoods Arctic Fox Silver Fox 32 5th Wheel Trailer  

Lets begin with the two leads that exit each brake magnet. One lead from each magnet needs to ground to the trailer frame. The brake magnets carry no polarity, so it does not matter which lead is grounded, and which lead is connected to the brake…

Humming in the drums means the magnets are getting power and you do not need new ones. If you have a proportional brake controller it will not engage while stopped because it needs the inertia from the tow vehicle to know when to activate. If you…

I would start by using a circuit tester, item #PTW2993 if needed, to check the wiring going to and coming from the brake controller. There are 4 wires that will need to be checked. White - Ground Red - Stoplight Switch Black - 12 Volt Constant Power…

Trailer brake magnets actually are not polarity sensitive. That means either wire lead can be the positive as long as the other wire is grounded.

I went out to the warehouse and pulled a Trailer Brake Magnet for 10" Hubs #BP01-110 and took some measurements for you. The brake magnet lead wires are 16 gauge wires and they measure 18 1/2 inches long.

The gauge of wire used in the magnets part #BP01-110 is 16 gauge. The part #DW05744-10 is a kit of 10 connectors that fit that wire gauge.

First thing I'd need to know is what kind of brake controller do you have? If it's time delayed the braking power is going to ramp up stronger and stronger till it reaches a pre-set amount. Typically when coming to a stoplight towing a…

In order to remove the hub/drum on your trailer you will want to first remove the spindle nut. Once the spindle nut is removed you are going to want to take a hammer and tap the outer portion of the drum as well as the hub face a few times to break…

Torque specs for wheel lug nuts will vary depending on the diameter of the lugs, type of lug nut and the wheel's material. The linked chart details the recommended torque for many combinations. Dexter Hub/Drum #84546UC3 has 1/2-inch studs and…

You are correct, you should only be getting output when the brake is applied, or the override switch is activated. It sounds like the controller might be bad, but to make sure, you should probably bench test it before tossing it. Use a circuit…

The torque for the Dexter Trailer Hub and Drum Assembly - 6,000-lb and 7,000-lb Axles - 12" - 5 Spoke Utility #8-174-5UC3 is not specified by the manufacturer. For 9/16 inch studs, the typical lug nut torque will be 120-140 ft lbs based on most…

The Dexter Nev-R-Adjust electric trailer brakes can be manually adjusted. There are a couple teeth of the adjustment wheel that are exposed just under the lever that you referenced. I have attached a photo showing the teeth. You will likely need a…
