A disc brake comprising a holder secured to a nonrotatable part of a vehicle, a first pin secured to the holder and extending in the opposite direction therefrom with one end portion straddling the circumference of a rotatable disc, a second pin secured to the holder and extending in the direction separating from the disc, a pair of friction pads on the opposite sides of the disc, a caliper slidably supported on the second pin and the other end portion of the first pin, and a third pin mounted on the caliper and spaced from the first pin in the direction of the circumference of the disc and supporting one ends of the friction pads, the other end of at least one of the friction pads being slidably supported on the first pin. The present invention enables reduction of the size and the weight of the holder. Further, the pad replacing operation can easily be performed without releasing the connection between the caliper and the holder.
