Disc vs. Drum

The surface area note is a worthy note and should be noted that a brake drum has the abilty to stop very well. Now here is the major advantage of disc, heat displacement or getting rid of heat.

Drum do not get rid of heat so fast vs. discs. Or at least should be the case. Well vented discs are better and in repeated applications, do well over drums.

Cooling the brake system with any set up will provide a great advantage in brakeing. If you can route a hose to cool your drums, they will retain better braking just like a disc.

Though I have not seen vented drum brakes yet. (Hummmmmmmmmmmmm)

I'm still running all drums on my Duster with the V8 swap done. I increased the rear drums to 11 inchs from the stock 9 inch at the rear. 9's are still up front.
