How to Choose the Correct Brake Assembly for Trailer Axles  

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…

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…

There really isn't a particular maximum trailer weight that is used to determine when brakes need to be added to both axles of a tandem axle setup. While I do still recommend checking your local laws, I am also not aware of any general laws…

Since you have 5,200 lb axles you will need 5,200 lb brake assemblies which we have a set for that with the part #AKEBRK-6. Not only is this the correct rating but a lower capacity assembly like 3,500 won't fit as the diameter would be too…

It sounds like there is a short somewhere because you should not be getting fluctuating voltage readings. Usually this is caused by a dirty/corroded trailer connector and/or a loose wire. Make sure the truck and trailer side connectors are clean…

The attachment bolts for a 5-bolt brake assembly should be torqued to 30-50 foot/lbs. This will ensure your brake assembly #AKEBRK-7-SA is secured correctly. If you don't have a torque wrench, I recommend the Powerbuilt Dual Drive Torque…
