A spreading spring for a floating-caliper or a fist-type caliper spot-type disc brake for automotive vehicles, comprising a spreading spring portion (30) which extends substantially in axial direction and forms two legs (34,36), the end portions of the legs (34,36) abutting on backing portions of brake pads (16,18). A resilient bracket (28) connected thereto extends substantially in circumferential direction and forms two legs (54,56) with the ends of the resilient bracket being supported on retaining pins (22,24). To accomplish favorable force distribution of the spring without impairing the function of the brake, the legs (34,36) of the spreading spring portion (30) are of different length, the ends of the resilient bracket (28) contain indentations (58,60) which provide contact points for abutment of the resilient bracket legs (54,56) on the respective retaining pins, and that indentations (58,60) are disposed on that side of the resilient bracket (28) which is close to the longer leg (36) of the spreading spring portion (30).
