1. A braking system comprising:
a fan that applies a braking force to a vehicle when the fan rotates; and
a gearset that is coupled with the fan and an axle of the vehicle to rotate the fan at a first rotational speed based on a rotation of the axle that rotates at a second rotational speed, wherein the first rotational speed is different from the second rotational speed, wherein the fan applies the braking force when the fan rotates at the first rotational speed.
