What's the easiest/best way to upgrade my brakes? I have a fairly stock 84 K10 with a 305 engine. I'm worried about my brakes overheating and failing while hauling a trailer or firewood. I don't know if that's likely to happen because I'm not overloading the truck, but I would like to be able to have extra assurance that I'll be able to stop the truck. How can I upgrade the brakes without getting into a big mess or big money? Do I change the calipers? Or the rotors?
