how, why are those better?
i don't see the advantage... in normal driving, i guess there isn't much difference? but the system i posted always has the right amount of brake pressure applied without any manual adjustment (don't want to overbreak a trailer), and the main advantage is when going downhill. you can just put the car in 2nd or 3rd, and let it roll. the trailer will press against the tongue and brake itself just enough to keep the same speed as the car. with the electric system the trailer will just speed up the car? and you'll constantly have to press the brakes
Except it actually doesn't, and there's no easy way to adjust it. The electric controllers are easily adjustable for load, the hydraulic ones are not. Also, you have the problem of getting the thing to work in reverse. There's a reverse lockout available for the hydraulics, but that's not exactly a great solution - especially if you're on a ramp or incline. In addition, getting it to work with a fail-safe system that applies the brakes if the trailer disconnects from the tow vehicle is problematic at best whereas it's easy on an electric system. Electrics are also far more reliable.
