PURPOSE: An auxiliary brake device is provided to separate friction between the ground and a wheel through being exposed and covering a wheel in used case by comprising a friction panel in the front side of a driven wheel in a car. CONSTITUTION: An auxiliary brake device comprises a brake panel(31), a brake panel actuator(32), and a controller. The brake panel is entered between the ground and a driven wheel of a car(2). The brake panel secludes direct contact of the ground and a driven wheel. The brake panel actuator operates the brake panel. The upper side of the brake panel contacting with a wheel is made of a smooth material having small frictional coefficient. The controller monitors the driving state of a car and transfers operation signal to the brake panel actuator.
