Question:

Hello, I have 2016 MMDI 6x10 scissor hoist tandem axle dump trailer with hydraulic surge brakes—yes, it was a Home Depot rental. My plan is to convert the surge brakes to electric. My question is, assuming the drums are in good shape, are they compatible with electric brakes? The brakes I’m considering are AKEBRK-7-D. The markings on the drums are “AXLETEKNOLOGY BD2-655 X F 44 15”.

Hey Lawrence thanks for the information! I wasn't able to find any good pictures of the inside of your Axle Tecknology BD2-655 drums. What you'll need to do is pull one of the hubs off and look at the inside. If they're smooth like the item # AKHD-655-6-K hubs you won't need to replace them. If they're rough or have casting marks they won't work with electric brakes because of the magnet not getting enough contact to expand the brake shoes.

The Trailer Hub and Drum Assembly item # AKHD-655-6-K will work as a replacement hub.

The etrailer Rust-Resistant Electric Trailer Brakes item # AKEBRK-7-D will fit your Axle Tecknology BD2-655 drums. You will want to verify your brake flange has a 5-bolt mounting pattern.

I recommend replacing the mounting hardware with the item # BRKH12. This will do one axles worth of brake mounting bolts.

Here are the rest of the parts you'll need to add electric brakes to your dump trailer. You'll have to change the 4-way connector on the trailer to a 7-way connector using item # H20044 and add the junction box item # 38656 to make all the connections. This junction box puts all your wiring in a secure location.

You'll have to run item # 10-1-1 wire from the junction box to each electric brake assembly using heat shrink butt connectors item # DW05745-5 for a weather tight connection.

As far as wiring goes the last thing you're going to need is a break away kit item # 20400, which will engage the electric brakes should your trailer ever become disconnected from your tow vehicle.

If you have any additional questions go ahead and throw them into the comment box below.

Hey Lawrence, did you get a chance to check the inside of your drums to see if they’re smooth? I'm curious to know how the conversion to electric brakes is going for you. Your experience could really help others looking to make similar upgrades!
