How Do I Determine What Electric Brake System Works With My Trailer

Published 11/11/2021

Question:

want to replace 10 electric brake system on a 1989 trailer... I think its 10,000GVW with two axles. Older e-brakes do not work, How can I tell axle capacity is it stamped somewhere? or just take 1/2 of GVW ? Thanks

Nowadays you would be able to find the axle capacity stamped on your axles, but that was not always the case. If you are unable to find that information on your axles, you still have other options. The first thing I would do is try to determine the make and model of your trailer, since you already know the year, and contact the manufacturer. A picture of the trailer and/or a description might help determine the axle you have on your trailer. If that does not work, there is one more option, but you may have to work backwards to get the information. This will also be the most time consuming option. You will have to find out what bearings and hubs you have and find those serial numbers. When you find that information. if you provide us with the bearing numbers we can do the rest.

More often than not, that size axle with 10" electric brakes is usually rated for 3,500 lb - 4,400 lb axles. If you have a 10" X 2-1/4" brake mounting flange is a 4 bolt pattern, any of our 10" X 2-1/4" will work for your you. If this is the case, I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K, part # K23-478-479. These brakes adjust automatically to deliver the best performance. The kit comes with the left and right hand assemblies.
