I will do a search on the threads here and learn!
the material used in 'dust-free' pads creates a light colored dust which doesn't show on the wheels. the softer the material equates to a shorter the life span and distributes a darker material/residue visible to the eye.
here is some general info from the manufacture...
Rotex Gold is the finest Kevlar metallic pad to date. It offers excellent stopping power, combining top-rated performance with a long service life. The friction material blends Kevlar with metallic soft steel wire and powdered sponge iron for maximum heat transfer, and silver virgin graphite for smooth quiet performance. This 60% metallic blend reduces vibration which causes squeal, and runs virtually dust free eliminating the common problem of "black dust" on the wheels. Perfect for drilled or slotted brake rotors.
