Once again, the organic pad zealots are poisoning the mind of the American motorist. Metal pads do not score rotors more than organic ones. Rotor scoring is mostly caused by
(1) a malfunctioning caliper,
(2) a pad that has hard impurities in the compound or
(3) a warped rotor that is riding against a pad edge.
A metallic pad is made from fine steel wire (like a Brillo pad) and powdered sponge iron. Both of these metals are softer than the rotor surface. And that's the truth.
