brake controller output
I have a 2012 Ford F250 with the integrated brake controller. It does not seem to work as well as it did when new. Cannot lock the brakes anymore. (same trailer) Ford says controller checks out fine...

BenK, i think they are talking about voltage, not ABS.
From what I surmise, the on and off pattern of the brake controller is not for ABS, I was not thinking that, but for voltage. Sounds like the brake controller puts out the full 12 volts, but when it cycles on and off quickly it roughly equates to a lower voltage. Am I correct here?
So, 50% on 50% off time-wise yields a kind of dirty 6 volts (is what I assume). This happens too fast for the mechanical brakes to respond to, so the effect happens at the brake (the spring, pad and magnet).
If I understand… The brakes are powered by the movement of the wheel. The brake drum rotates around the stationary brake pad. The magnet pushes the pad into the drum and friction pulls the pad, or wedges it almost, into the braking action. Compared to the electronics on the other end, this is a slow process.
Someone add to this as is all I understand so far…
