No genius, my point was that new brakes won't help when you start down a steep grade in the wrong gear. When in a lower gear, a brief tap on the brakes every now and then will do the trick. When in to high a gear, there isn't enough braking in the world to save you. You know zero about trucks. There isn't a brake system in the world that will stop a semi in a high gear going down Wolf Creek, or any other pass. What do you suppose will be the official cause of the crash? My money says driver descended in to high a gear. You really don't know much about trucks, do you. I certainly hope you don't have a CDL.
