Anti-lock brakes? Not sure that I see the connection. Anti-lock brakes are designed to take you right to the brink of lock up and then apply no more braking force, regardless of how much harder you press on the brakes. "Suicide levers" have no such feature. They just dull the braking action, typically leaving you quite far from the amount of force needed to lock the front wheel. As long as the bike rider knows the limitations, they are not a problem to use for slowing down when you are descending into a turn or similar, but the problem comes from less knowledgeable riders who are not aware of their limitations. I'd really encourage you not to put them on a bike for your daughter.

Rather install in-line brake levers instead.
