PURPOSE: A brake device of a vehicle is provided to make an excellent braking performance through a simple structure of a braking system, so the braking force and reliance are improved. CONSTITUTION: A brake shoe(2), which is contacted to the inside of a brake drum(1) and expanded, generates the braking force. A braking rod(3) is equipped between the brake shoes and moved to a straight direction by the brake working force. A stick device sticks the brake shoe to the brake drum. A pressure generating device consists of a rotary pressing wheel(6), a hydraulic pump and an oil tank(7), and generates the pressure as the straight movement of the braking rod. A wheel cylinder(4) sticks the brake shoe to the brake drum through the pressure from the pressure generating device.
