The invention provides a car group brake method for a car group brake device of a railway station track. For car groups required to be braked, brake force is applied on the portions, behind the axis vertical lines, of wheels, or small brake force starts to be applied when the wheels enter the effective range of the brake device; and the brake force is increased after the wheels entirely enter the effective range of the brake device, and the brake force is increased after the portions, in front of the axes, of the wheels move out of the effective range of the brake device. When the brake device applies brake force on the portions, behind the axis vertical lines, of the wheels, the brake force can form downward force and backward resistance in the tangential direction of the braked points of the wheels; and the downward force in the tangential direction is converted into force for tightly pressing a basic rail downwards by the wheels, so that compared with a wheel front point brake manner of an existing brake device, by means of the car group brake method, the force generated by the brake force for lifting the wheels is eliminated, the downward pressure for pressing the basic rail downwards by the wheels is increased as well, accordingly the friction resistance of the wheels and the basic rail is increased, and the brake capacity of the brake device in the unit length is improved.
