I live about 50 yards from a road that accesses a major highway in Nevada so there’s a lot of truck traffic on this road. The section I live next to is a very gentle slope down from an overpass over a railroad and about every other truck that comes down this gentle slope flicks on the jake brake for some reason. I understand the point of a jake brake as I used to tow a heavy fifth wheel and the exhaust brake on my ram was amazingly useful (yes I’m aware that they function differently, but the overall result is the same). My issue is that this slope is very gentle and only about a quarter mile long, so why with the loud Jake brake when you could just tap your service brakes a bit. Is there something I’m not understanding about the operation of these trucks?
