First off, love my foreman, but drum brakes on the rear??? Ridiculous in this day and age. I have been looking at a rear disk brake upgrade kit and was hoping to get some feed back before I drop 400 bones. Just for comparison, a new drum for my machine is over 200. Anybody installed one? I ride a lot of swamp and deep water so drum brakes don't last long. Here is a vid with the hero cam on from a couple years ago.
