First glad you are fine.
Next, welcome to iRV2.com.
All brake controllers are different and I as well as some others have had bad experiences with the inertia based controllers. What brand and model do you have.
The Jordan 2020 was a great direct proportional controller but the design was bought and it has not been back on the market. My Jordan dies and I replaced it with a MaxBrake which is a hydraulic over electric proportional unit. It is without a doubt, the smoothest brake controller I have used.
Let us know what controller you are using. But the best place to start is the instruction sheet for the controller. The inertia based units are hard if not nearly impossible to get set for smooth braking in the city and then for highway use.
You will find most of the people using the inertia based units as they are more readily available and much cheaper.
