A disc brake including a stationary member having a pair of legs spaced in the direction of the circumference of a rotatable disc and straddling respectively the outer circumference of the disc to define respectively thereon pad guiding portions which are interrupted by respective grooves in the legs, a pair of friction pads disposed on opposite sides of the disc and slidably supported on the pad guiding portions, a caliper supported slidably on the stationary member, and a pad spring provided between the stationary member and the friction pads. The pad spring is retained on the stationary member and has a stop for restricting the sliding movement of at least one friction pad approaching toward the disc.
