The present invention is a vehicle disc brake for which incorrect installation of a friction pad can be prevented with a simple structure. The disc brake is provided with incorrect installation-preventing parts with which, if a friction pad () is installed with an incorrect installation orientation when a pair of tabs () provided on the disc entry-side and disc exit-side of the back plate () of a friction pad () is installed into pad guide grooves () formed on a caliper body (), the tabs bump into the caliper body () and prevent the incorrect installation. The incorrect installation-preventing parts are formed from caliper-side recesses (), which are formed in the pad guide grooves () towards the center of the caliper body, and tab-side protrusions (), which have shapes that correspond to the caliper-side recesses ().

A caliper bracket of a vehicle disk brake includes an axle coupling part, an extension part, a caliper attaching part and a swing arm coupling part. The axle coupling part is disposed on an opposite side to a disk rotor and is attached to a rear wheel axle passing through a center of the disk rotor. The extension part is extending from the axle coupling part. The swing arm coupling part is provided on the other side part of the extension part in the longitudinal direction and is coupled to a swing arm. The extension part is formed to linearly extend from the axle coupling part, and the swing arm coupling part is formed to have a cuboid shape protruding toward the opposite side to the disk rotor and capable of fitting with a coupling groove member provided for the swing arm.
