車両用デイスクブレーキ。 A cylinder hole that is long in the circumferential direction of the disk is provided in the action part of the caliper disposed on the side of the disk rotor, and a piston inserted into the cylinder hole moves the friction part to the disk rotor. In a disc brake for a vehicle that presses, the opening area of the cylinder hole on the disc retraction side from the pad radial center line of the friction pad is formed smaller than that on the disc retraction side, so that the opening area of the cylinder hole on the disc retraction side of the piston is smaller. A disc brake for a vehicle, characterized in that the pad pressing area is set smaller than the disc retraction side.
