Question:

I would like to replace the coupler on my a-frame hitch. I have surge brakes now and it seems like a good system when everything is working properly. I dont know how difficult it is to change that to a conventional trailer braking system. I do have trailer brake controls in my truck. I was thinking about replacing the surge brake system with another surge brake system, but if it is more cost effective, I would be willing to replace the surge brakes with conventional trailer brakes.

There is less maintenance with electric brakes compared to hydraulic brakes so switching to an electric braking system would help in that regard and since you already have a brake controller there isn't any additional major costs.

You could also still use the same coupler you have now though it will still move in and out. Most people go ahead and change out the coupler too. We have a lot of A-frame couplers depending on the capacity needed.

For the brakes the trailer will need to have a 7-Way connector, if it doesn't already, and wiring to go back to the brake magnets on the new electric brakes. You can use wire # 12-2-1 sold by the foot.

To determine which brakes fit I will need to know the size of the brakes you have now. You can pull off a hub and drum from your trailer and measure the inner diameter and the width where the brake shoes make contact with the drum.

You may also need to replace the hub and drum assemblies. Some can be used with either hydraulic or electric brakes but not many. Most are just for one or the other type of system. It may have this information stamped somewhere on the drums you have. If you are not sure it would be best to replace them.

To replace the hubs I will need to know the inner and outer bearing numbers stamped into the sides of the bearings you have now. If you are pulling off a hub anyway to measure it then you will have access to the bearings. I will also need to know the bolt pattern of the wheels on the trailer. I have included some links that will help.
