1. Pad springs for a vehicle brake which are installed in a pad carrier to apply elastic forces in directions in which a pair of pad plates, each pad plate including a brake pad, is spaced apart from a disc when an operation of a vehicle brake is released,
wherein the pad carrier includes a leading side support frame, a trailing side support frame, an inner side support beam, and an outer side support beam, wherein the support beams connect the support frames, and
the pad spring is provided on each of the inner side support beam and the outer side support beam, and
wherein at least one among a width, a length, and a thickness of a retraction bar provided on one of the pad springs is different from that provided on each of the remaining pad springs so that different elastic forces from the pad springs are applied to the pair of pad plates,
wherein an identification part having a different shape is formed on each of the pad springs.
