This invention is disk brake which monitors braking positive pressure under braking state. It includes braking disk, brake shoe, lining board, butterfly spring, joining bolt, brake seat, hydraulic cylinder, adjusting screw stem and piston. The superior part of lining board has a big groove, which bottom has a blind hole. The joining bolt rod has two bosses. The bottom boss is welded in blind hole at bottom of lining board. The middle boss is arranged with sleeve, which bears butterfly spring. There is sensor between joining bolt and sleeve. Nut component is set above joining bolt. This invention can measure positive pressure directly under braking state. Positive pressure data multiplies friction coefficient and brake radius to get brake moment, in order to monitor brake moment and check total brake moment is whether or not bigger than 3 times maximal static moment. This invention has widely practicability.
