Dumb question but how do electric brakes work? I have a controller on my disco what happens between the time I put my foot on the anchors to having the brakes come on on the trailer. I understand how the actual brake part works just not the electrical side. ie is the controller hooked up the the brake light or is it driven by accelerometer? Is there a wire from the controller to the trailer or is it wire less? Are the brakes on/off or progressive.
I hired a car trailer the other day that had electric brakes but everything was self contained on the trailer so buggered if I know how it knew when to turn on or off.
