A caliper assembly for a disc brake of a vehicle, which assembly includes a carrier member, a disc, a pair of main pads attached to main pad plates forming a pad assembly, two pairs of pistons mounted to springs disposed within recesses which pass through the carrier member for pressing circumferential edges of the pad plates when the hydraulic fluid pressure supplied through hoses from the master cylinder compresses the springs and pistons, whereby since the pad plates are thus immobilized with respect to the carrier member, the caliper assembly reduces squeal noise due to non-vibration of the pad plate, and prevents the pads from non-uniformly abrading, thermotransforming, and changing properties thereof so as to highly increase braking efficiency.
