I think it has a little lever that flips over and locks the two brake pedals together. Then there should be another little lever right down there by the pedals that locks the pedals down when your push them. That is as good as it gets. You need to have your pedals adjusted so when they make contact with the brakes the pedals will be the same height. I normally use a gear or lower an implement rather than locking the brakes but that's just my preference.
