置。In a vehicle speed detection circuit comprising a vehicle speed sensor that electromagnetically detects the number of teeth of a gear-like rotor attached to a wheel passing in a unit time, the vehicle speed is detected from an output frequency of the vehicle speed sensor. When the circuit number is inserted, a wear sensor is attached to the friction member of the brake of the wheel and detects when the wear of the friction member has reached its usage limit, and a vehicle speed sensor is attached to the vehicle speed detection circuit. A wear detection device comprising: an alarm circuit that reports wear of the friction member based on the output voltage of the friction member.
