PURPOSE: A braking device, capable of efficiently cooling is provided to prevent the flickering of a disc by shortening a stopping distance by forming a friction contact surface to be continuously curved. CONSTITUTION: A braking device, capable of efficiently cooling comprises a brake pad(30) and a brake disc(20). A curved surface is formed on friction contact surfaces(24,32) of the brake disc and brake pad. When the brake pad and brake disc are contacted with one another, the brake surface is expanded by the continuous curved surface and the flickering of the disc is prevented. Each non-contact surface is formed on top and bottom of the friction contact surface.
