[censored]. On a car or light duty truck, drum brakes will fade
much more quickly than discs, period. There's nowhere for the heat to go on a drum, it's all trapped inside. A disc brake runs out in the open and any type of disc you'd be using on the front of a pickup truck would be vented, thereby allowing
more airflow and cooling.
Big trucks use drum brakes 'cause they have air operated braking systems as opposed to the hydraulically operated systems on cars and light duty trucks. I believe that the reason they don't commonly use disc brakes on the big guys (yet) is because of difficulties designing an air brake application system which will work properly with discs. In some cases, big truck drum brakes are also built without drum backing plates to allow airflow inside the drum to help brake cooling.
There are many places in a project vehicle where you can cut corners on budget-safety
isn't one of them and brakes are the biggest safety factor on the vehicle.
I would agree with one of the above posts with reguards to purchasing a complete matched package setup with all pieces together. It will be money well spent for sure. Best of luck with your project.
