Do you have surge brakes on your trailer now? I bought a new Ace custom aluminum trailer from Ace in Gibsonton Florida 2 years ago. It came with electric over hydraulic brakes . As folks say, IMHO it is the best system going. We have towed our boat, a Mako 201 back and forth from Florida to Ottawa,Ont. I love the system. It may be more than you are looking to do but we are pulling around 6000 lbs on the back of a 2008 F-250 and when I need to stop you can really feel the trailer help the truck. I know 6000 lbs is not a lot for this truck but we have 15,000 miles on this trailer and I am really happy with this system. It came with Kodiak disc brakes on both axles and stainless tubing to the calipers.
I looked at a comparable trailer in Port Charlotte. The guy tried to tell me I didn't need brakes. I said thanks for your opinion and left. A good trailer guy is sometimes hard to find.
Etrailer.com has a good supply of parts. The one drawback to electric over hydraulic system is that it doesn't operate on all brake controllers. There is a Titan adapter some controllers need to run the pump. It may be way more than you want to do but for my application , with the high mileage I put on my trailer , the cost was worth it. There is my 5 cents Canadian so 3 cents US. Good luck with your project. The Kodiak calipers are very easy to work on. We blew a seal the last day before heading home and pulling the caliper and changing the hub took less than an hour. I had problems finding a grease gun. Should have been about 20 minutes. My Ace trailer came with the spare mounted on the winch tower on a spindle on a spare hub. Brilliant thinking. If you do a lot of long distance traveling a $35 dollar hub makes a lot of sense to carry.
Hope I didn't run on too long.
