Re: Hydrolic to Electric Brake Conversion questions.
If you have a hydraulic system you already have surge brakes. That's why they are called "surge brakes". If that's what you already have, why would you want to change them. It can certainly be done buy why? Salt water is tough enough on non-electric components, why would you want to add another system for it to attack. Electric brake backing plate assemblies and hubs are about $200 give or take a little depending on size. They range in size from 7-inch, 8-inch, 10-inch and 12-inch. You would need to wire the trailer, add an emergency disconnect package which is a small battery and switch that actuates the brakes should the trailer come unhitched. Those are required by law in most states on trailers with electric brakes. You also need a brake controller in the vehicle (50 - 150 bucks) depending on type. With surge brakes the hubs and backing plate assemblies are basically the same price as electric give or take a little. No electrical wiring or controller is required, but you do need a surge brake coupler and the necessary hydraulic plumbing to each wheel. Google Electric Brakes or Surge Brakes and read about the various systems and to find links to various suppliers. Try here on iBoats, Northern Tool, Champion Trailer, etc.
