The drum brakes on my 37 Buick served me well for 40 years UNTIL I got caught in Kansas City during a monsoon. The drums were actually under water and though I had full pedal I had no brakes. For 99% of people with vintage rides I'd stay with drums but mine gets driven from coast to coast and Mexican to Canadian border including traversing the length of the Grand Teton mountains. Just one 40 year event had me put on front discs so I will always have stopping power regardless of conditions. It would take a really big guy or at least a small gun to force me to go back to all drums.
