In practice, sliding calipers work fine for anything except for hard raceing since once the pad is worn in, it will just continue to wear at a slight angle. If the pad makes contact onthe inner edge of the rotor before the outer as shown in the old pic, it indicates a binding or dragging problem. Many shops would take one look at those rears and just quote calipers and hoses right off the top.
