Disc Brakes or Drum Brakes

Drums work fine for stopping once from 80 mph or less. Stops from very high speed or repeated stops, without enough time to cool, like road-racing or excessive braking on mountain roads (FL drivers in NC) can over-heat them and cause the friction linings to "fade" (melt). Most problems with drums are due to poor maintenance. They are touchier than disks to oil or other junk on the shoes since they have a (non-linear) self-jamming effect (why you don't need vacuum booster). That can cause a pull to one side, as can somebody installing the shoes wrong (short lining should be on fwd side).

I have drums on all my 60's Mopars, and no issues, though the 9" drums are a bit marginal. The 11"x3" front drums on my C-body will haul down anything. I do plan to try disks later, but it sure isn't my top priority, and I won't spend $800 on it.
