Claim Text:
1. An active corrosion protection circuit for a brake disc-pad unit of a motor vehicle comprising: one of a metal disc and a pad adapted to selectively block said disc; a direct electric voltage source and an electric conductor connected to said direct electric voltage source and one of said metal disc and pad, so as to form an electric circuit causing a monopolar current flux between said metal disc and said pad when said pad blocks said metal disc, so that the action of the current is localized in a contact zone between said metal disc and said pad; a control unit, which controls the current based on a control signal indicative of contact between the metal disc and the pad; and in which the control unit is programmed to apply either a monopolar electric voltage to said one of the metal disc and the pad, or a monopolar current in the contact zone between the metal disc and the pad upon receipt of the control signal indicative of contact between the metal disc and the pad, the monopolar electric voltage or the monopolar voltage being applied intermittently during the time that the control signal is received, wherein the intermittent application of the voltage or current preserves the life of the direct electric voltage source.
