Surge Drum Brakes to Electric Drum Brakes on a 4,400 lbs Axle


It looks like my axle plate bolt pattern is offset top to bottom. Is there an electric swap for this style?


Expert Reply:

Yes, there are electric brake assemblies available for you to swap out your surge brakes that will fit your bolt pattern. It sounds like you have a 4,400 lbs axle that has a different 4 hole pattern. I linked a diagram of it below so you can confirm.

If this is what you have you are going to want the Dexter Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4,400 lbs item # K23-462-463-00. Or the never adjust Dexter Nev-R-Adjust Electric Trailer Brake Kit - 10" - Left and Right Hand Assemblies - 4.4K item # K23-478-479.

You will also need Deka Jacketed 2 Wire, 10 Gauge, Brake Wire - per Foot item # 10-2-1 to wire up your new brakes.

I recommend adding the Trailer Wiring Junction Box - 7 Color Coded Terminals - ABS item # 3375601101 to your trailer. This will consolidate and secure all of your trailer's wiring connections into one central easily accessible location. You will also need the 7-Way Molded Trailer Wire Connector, 4' Long item # H20043.
