1. A method of braking a vehicle, the method comprising:
determining whether a brake request signal is input;
determining whether an amount of change in the brake request signal is equal to or greater than a preset standard;
comparing a slip ratio of a front wheel portion with a slip ratio of a rear wheel portion in response to a determination that the amount of change in the brake request signal is equal to or less than the preset standard;
reducing a braking force of a shaft having a large slip ratio of the front wheel portion and the rear wheel portion and increasing a braking force of a shaft having a small slip ratio, based on a comparison result after the comparing of the slip ratio of the front wheel portion with the slip ratio of the rear wheel portion;
moving a braking distribution ratio formed based on the increased or reduced braking forces of the front wheel portion and the rear wheel portion from an actual braking curve to an ideal braking curve, after the reducing of the braking force of the shaft having a large slip ratio of the front wheel portion and the rear wheel portion and the increasing of the braking force of the shaft having a small slip ratio; and
braking the vehicle based on the braking distribution ratio on the actual braking curve or the moved braking distribution ratio on the ideal braking curve.
