One of the reasons the wire (which is nesserary) may be getting to close to the curb chain is that the curb chain is not tight enough. For testing this, let it hang freely on your horse then put your three fingers (flat against the horses jaw) in there to see if it is slighly snug. The wire keeps the side from flipping over up side down while pulling back.
