How to Determine What is Needed to Switch from Hydraulic to Electric Brakes

Question:

I have a Rolls Marine boat trailer,model # w2360t 5180 lbs max tandem axle that now has surge hydraulic bakes on one axle. I would like to know if there is a kit to make this an electric braking trailer? And if so,what control would I need for them? Thank you for any help... P.S. picture is of my boat on said trailer,I have a picture of the model and serial number,but they are on my phone,but can be sent if needed.

There are parts you can put together to switch from hydraulic to electric brakes, though not a kit. And we don't have any way of knowing what parts will work on any specific trailer, but it's pretty easy to determine how. you need to know the weight rating of your axle, the bolt number of your brake mounting flange as well as the depth and diameter of your hub and drum.

For example, you mentioned a max weight of over 5,000 lbs so your trailer axles could have 3,500 lb axles and drums that measure 10" diameter x 2-1/4" deep. If so, and you had a 4-bolt mounting flange you would need the Electric Trailer Brake Kit # AKEBRK-35-SA with mounting hardware # BRKH10B.

I have added a link to our selection of electric brakes for you once you know what size your drum is, or you can let me know and I can find the right one for you. I have also linked a help article on what you need in order to add electric brakes.

Keep in mind you'll also need the Hopkins Engager Push-To-Test Trailer Breakaway Kit # 20400 and trailer wiring for your trailer with the etrailer Trailer Wiring 7-Way Upgrade Kit with Junction Box and RV Style Connector # e99011.

To control them you will need a brake controller like the Prodigy P3 # 90195, and your tow vehicle would need a working 7-way.
