Claims

[Scope of utility model registration request]

In a pad wear detection device for a disc brake that is configured to detect the amount of movement of the caliper relative to the anchor plate and electrically warn the wear limit of the pads, the side end surface of the anchor plate 1 is made of a thick metal material to provide high rigidity. A wear detection switch 10 has a mounting base 12 which is formed to have a shape and is removably fixed thereto, a space adjustment ring 13 is sandwiched and removably fixed to the mounting base 12, and a spherical ball contact 15 is provided on the top of the head. and a sensing tool 11 having a sensing surface 24 formed as an inclined surface to be in contact with a ball contact 15 fixed to the gear ripper 3.
This pad wear detection device for a disc brake is characterized in that the pad moves together with the caliper 3, and in the wear warning area of the pad 6, the detection surface 24 comes into contact with the ball contact 15 to issue an alarm.
