PURPOSE: A structure of a disk brake caliper is provided to prevent the malfunction of a brake by reducing the vapor lock in oil by separately exhausting high temperature generated during pressurizing a disk pad fixed in a disk. CONSTITUTION: A structure of a disk brake caliper comprises a piston(10) and an exhausting unit(30). The piston is inserted and installed on the caliper around a disk pad. The piston pressurizes the disk pad. The piston comprises a piston head(20) supplying sealing force through reciprocation. The exhausting unit exhausts friction heat generated while pressurizing a disk pad on the disk. The exhausting unit reduces the temperature of a caliper.
