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 life of the brake pad. The number one cause for customer returns are 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 all of its Posi Quiet brake pads. This additional process forces any impurities out of the friction material and pre-burnishes the pads to greatly accelerate the break-in process. All Posi Quiet brake pad friction formulations are asbestos free and are available in three application specific compounds complete with all necessary hardware for installation where applicable. Longest wearing most advanced material available; 100% scorched for easy bed-in; 100% shimmed to eliminate noise and vibration; Stable friction performance across a wide temperature range; Hardware included; Where applicable 2001 - 2003 BMW 525i, 1996 - 2003 BMW 528i, 2001 - 2003 BMW 530i, 1996 - 2003 BMW 540i
