Claims

[Scope of Claim for Utility Model Registration] 1. An inner caliper and an outer caliper each having a slidable piston and integrally connected to each other, and an inner caliper and an outer caliper formed with an opening on the outer diameter side inside the inner caliper and outer caliper. Opposing type disks consisting of inner pads and outer pads, which are arranged to sandwich the rotor from both sides in the axial direction in the pad insertion space and to face each of the pistons, and which are pressed against the side surfaces of the rotor by the pistons to generate braking force. In the brake, a pad is attached to an outer diameter side end of a back plate of at least one of the inner and outer pads so as to protrude toward the rotor by a predetermined amount, and is attached to the rotor when the at least one pad is worn to a friction limit. It consists of a wear detection tool that comes into contact and breaks and the metal wire inside it is cut, and a detection circuit that is connected to the metal wire and detects when the metal wire is cut. A pad wear detection device for an opposed disc brake, which is characterized by: 2. The inner and outer pads arranged in the pad insertion space are inserted into the pad insertion space by a retainer member that covers the pad insertion space from the outer diameter side and is attached to the inner and outer calipers. A wiring hole for passing an electric wire connecting the metal wire and the detection circuit is formed in a portion of the retainer member close to the wear detection tool. A pad wear detection device for an opposed disc brake according to claim 1.
