Converting a 5th wheel trailer from electric drum brakes to electric-over-hydraulic disc brakes will require a couple of items: the disc brake kit of hub/rotors and calipers, a brake line kit, an electric-over-hydraulic actuator, a breakaway kit and a brake controller such as the excellent Prodigy P3 # 90195. The linked article covers each of these items and is a good starting point for planning your project.

A link is provided that will show you all disc brake kits with the 8-on-6-1/2-inch bolt pattern. These kits start at a 7K rating, use 13-inch rotors and are suitable for 16-inch and larger wheels. You have options for the materials and finish, including raw finish, protective E-Coat, Dacromet or stainless steel.

For a tandem axle brake line kit you'll use Demco # DM5425 and for an electric-over hydraulic actuator you can use the CTS # HBA16. For a breakaway kit I suggest Tekonsha # 50-85-313.

Finally the brake controller I recommend is the Tekonsha Prodigy P3 # 90195 which is among the easiest to use and most reliable units on the market.

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
