I just got a new truck that has the brake controller that came with the truck. I don't understand the controller. What is brake gain and output? I have 2 apparent things I can control, the gain and the output. What is gain and what is output? Before I had only one control and it did not read out any numbers. This new one does and I am wondering what it actually means.

Is this a factory brake control or aftermarket under dash unit? Mine an aftermarket unit and has a gain adjustment and shows numbers when I hit the brake to let me know how much the control is putting out... On my horse trailer I adjust it to 3.8 but when I haul my hay trailer I turn it up to around 4.4 or so. I am guessing if yours is a factory control the gain is going to be like mine and the output reading will show how much brake is being applied when you hit the foot brake.

It is a factory brake controller on a 2013 Chevy 2500. I think you can control both the gain and the output? I was wondering which one did what and how they should be adjusted.

Thanks, now one last question. How come I have 2 control "buttons". One I can increase with a button (the gain i believe) and it goes up in increments, the other "button" is a slide type button which you squeeze over left or right and it has a mark that is like a lesser arrow, one higher.

Horsey1, new trucks come with a manuel if you can interpret it which in my case, nobody could, hence the reason for asking on this forum. Kind of like a man asking for directions, they don't!

Re: the brake control - I just purchased a 2013 GMC 2500HD. Sounds like my brake controller. If I remember correctly the one button changes the amount of braking power so to speak. The slide is to be used for applying the trailer brakes without using the truck brakes.
