    Abstract: A disc pad brake system (10) is provided for longitudinally displacing one or more friction pads (14) into force contact with a rotating disc member (12). A caliper assembly (24) includes a caliper housing (26) within which there is displaceably mounted a piston member (18) having a bore (20). The piston member (18) is longitudinally displaceable in a reversible manner for contacting and displacing the friction pads (14) into contact with the disc member (12). The caliper assembly (24) includes a pair of carrier plates (28) having opposing first and second surfaces (30 and 32) with the first surface (32) of the carrier plate (28) being coupled in fixed fashion to the friction pads (14). At least one resilient pad member (34) is displaceably secured to the second surface (32) of the carrier plate (28) for contacting the piston member (18) during a braking operation.
