Common knowledge says disc brakes are better, and there's obviously a great deal of truth to that since manufacturers have been moving away from drums slowly but steadily over the years. The problem is, short of having a skidpad, the difference isn't so obvious to me in real-world use. Can anyone point out exactly what makes the disc setup superior?
