How to Choose the Correct Electric Brakes for 20 Foot Flat Bed Trailer


I am shopping for electric brakes for my trailer. It is a 20 ft, flat bed trailer with 15 inch wheels and a capacity of 7,700 lbs. What are my options? Thanks Dennis

In order to find the correct electric brakes for your trailer you are going to need to know the axle capacity. You should be able to find this on your axle tag. Once you have this information you will be able to choose the correct brake assemblies for your trailer.

For example, if you have tandem 3,500 lb axles then you could use the Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 3.5K # 23-468-469. These are self-adjusting brakes that fit a 10 x 2-1/4 inch drum and a 4 bolt brake mounting flange.

If you found you had a single axle with a 7,000 lb capacity then you would be looking at the Dexter Electric Trailer Brake Kit - 12" - Left and Right Hand Assemblies - 7,000 lbs # 23-180-181 instead. These would fit a 12 x 2 inch drum and have a 5 bolt brake mounting flange pattern.

I have attached some review videos along with a link to all of our electric drum brakes that can be filtered down by axle capacity for you to check out.
