there are only advantages to having them on the back of the fork. having them on the back means the rotational resistance of the brake against the rim pulls the brake posts inwards, against the brakes themselves, you get better braking. On the front, the braking forces would make the posts splay outwards, reducing the effectiveness of the brake.
