Posi Quiet brake pads are manufactured using the same positive molding process utilized by Original Equipment suppliers. Positive molding uses extreme pressure to compress the friction material and bond it to the backing plate. This process assures consistent friction material density throughout the pad, resulting in even wear and performance characteristics throughout the brake pad's life. The number one cause for customer returns is noise and vibration. Centric Parts has recognized these issues and is constantly improving its products to eliminate these issues. Posi Quiet brake friction features either precision cut or shaved backing plates and mechanically attached shims; these small details ensure proper fitment in the caliper and virtually eliminate noise associated with pad vibration. In addition to these features, Centric Parts has added a scorching process to its Posi Quiet brake pads. This additional process forces any impurities out of the friction material and pre-burnishes the pads to accelerate the break-in process.
