Centric Posi Quiet Ceramic pads offer extremely long pad life and are Centric's lowest dust pads, keeping wheels cleaner longer. Quiet and rotor friendly. High fade resistance for performance street driving. Not for track use. All Posi Quiet pads have precision cut backing plates and composite shims to ensure proper fitment and reduce noise associated with pad vibration. 100% scorched to drive out impurities and speed up the bed-in process. Manufactured using the same positive molding process as Original Equipment suppliers. Positive molding uses extreme pressure to compress friction pucks and bond them securely to the steel backing plates. This assures consistent friction material density throughout the pad, resulting in more even wear and better performance throughout the life of the pads. It also reduces the risk of pad delamination under extreme conditions.
