And if I'm cruising along and just want to lightly use the brakes to slow a tiny bit, that first the truck's brakes work and then the trailer brakes ramp up and kick in and can give too much overall braking effort and thus I immediately let off the brakes entirely.
Maybe it's just the way the beasty works and I need to get more used to it. Perhaps I could try playing with the settings a little?
A time delay brake controller like the Activator II usually has 2 settings. The braking power, and the rate of application. If you set the rate of application, say for 4 seconds, the the braking power will gradually increase to the maximum you have it set for in 4 seconds. Second #1, is .25%, second #2 is 50%, etc. If you need to make an emergency stop, then you will not get fulling braking power until second #4. If you set the rate of application lower, say 1 second, then you are gonna get 100% of the trailer braking when your brake pedal is depressed for 1 second, leading to abrupt stops when you just want to slow down.
Any time the brake pedal is released, the process starts all over again. You can have a high power setting and low rate of application, and maybe "pump" your brake pedal when trying to gradually slow down. Or you can have a slow rate of application and a hight power setting, and get in the habit of reaching down and applying the manual control when more braking is needed. The manual control usually brakes up to the maximum power setting you have set.....if that makes sense.
That type of controller was all that was available many moons ago, unless you had a controller that was actually attached to the brake pedal. Times have changed, and a controller that measures deceleration is a much better option these days.
