Surge brakes need maintenance just like any other mechanical item.
That said, I like the adjust-ability of electric brakes.
If you can manage switching out brake assemblies, then the wiring is not that hard.
You don't wire anything into the brake light circuit except brake lights and the trigger wire for the brake controller, if not pre wired in your vehicle.
What vehicle do you have? Most all trucks from the last 20 years are pre-wired for a brake controller under the dash and at the back of the truck (7 pin plug).
If your RV isn't it's not that tough.
