Not sure what causes it. Only happens when the trailer is loaded. Generally only happens with the brakes get hot.
Basically, I'm coming up on a light and I hit my brakes like normal. Everything is going OK, but when I slow down a bit, the trailer feels like it starts grabbing more and more until I barely have any pressure on the truck's brake pedal and the trailer is slowing me down.
It seems like the inertial sensor in the controller gets into a type of "feedback loop" where it reads the trailer slowing the truck down as MORE brake pedal pressure, so it applies more pressure to the brake, which it reads as more pedal pressure...so on and so forth.
Does this happen to everyone? Do I have too much brake dialed in?
I'm running a Tekonsha P3 on an Expedition. I have a 10,000# dual axle dual brake trailer. This is most noticable (or most disturbing) when I have at least 3,000# of stuff in the trailer.
I'm able to modulate the rig...it isn't unsafe. Just figured I'd ask if it is normal. I have never driven an electric brake trailer before my ownership of this rig.
