Issues with my Hopkins Brake Controller
I have the 47294 controller and I've been concerned with it's operation. It has a tendency to lock up while applying firm (non-panic braking) pressure while coming to a stop. I always know the trailer brakes work well because when they lock up it's like catching the landing arrest cable on a carrier. (not that I know that feeling, but imagine being thrown into the steering wheel unexpectedly).
This typically happens when traveling on secondary roads with a slight downhill grade and bumps. I'm assuming this has to do with the internal mechanical pendulum style mechanism.
The 47294 has a bad reputation with other owners I've seen writing reviews with it's "brake bump" feature that surges the brakes to 10 percent to prevent the trailer from bumping the tow vehicle when tapping the brakes. I've noticed that bump has a tendency to jerk the trailer back instead of making anything smoother. If I adjust the power on the brakes to prevent the 'jerk', then it doesn't adequately slow the trailer to a stop.
I'm considering upgrading to a P3, which uses a digital gyroscope for braking adjustments. Should this fix my problems?
