A brake structure of vehicle, characterized by a brake abrasion surface applied onto a braking device wherein the brake abrasion surface thereof is equidistantly defined by a plurality of crescent-shaped grooves that are partially overlapped at their ends to form a plurality of symmetrically intersecting points at the brake abrasion surface thereon; in braking operation, lining plates of the braking device are in abrasion engagement with the brake abrasion surface thereof, and, via the crescent- shaped grooves abrasively abutted against the lining plates, the frictional coefficient is increased so as to achieve better balance effect of the lining plates, avoiding the slipping and deviating of the lining plates in braking operation; besides, when the lining plates are abrasively contacted with the intersecting points of the grooves thereof, the frictional coefficient thereof is relatively augmented to a great deal, efficiently shortening the braking distance as well as boosting the driving safety and the torque output thereof.
