ABSTRACT:
An electro-mechanical brake achieves a safe traveling and braking with a high accuracy device for detecting a piston position at which a brake pad and a disk rotor contact each other. A pad contact position detecting device in which an electric circuit is not formed to prevent an electric current from flowing therethrough when a pad pressing force is not generated and the electric circuit is formed to enable the electric current to flow therethrough when the pad pressing force is generated is applied to the electro-mechanical brake. A pad contact position can thereby be detected accurately.
