Abstract
A method of controlling a brake force in a brake system including a front wheel system and a rear wheel system, includes the steps of: operating a brake in the front wheel system by using a hydraulic pressure corresponding to an amount of brake pedal operation; and controlling a wheel speed of the rear wheel system via a feedback mechanism to match a wheel speed of the front wheel system.
