Claims

[Scope of utility model registration request]

A braking pad 2 facing a braking disc 1 is fixed to a piston rod 6 integrally provided with a piston 5 fitted in a piston chamber 4 of a caliper 3 in a disc brake, and is fixed to a piston rod 6 that is integrally provided with a piston 5 fitted in a piston chamber 4 of a caliper 3 of the disc brake. A hydraulic pressure line 7 for brake release is connected to the piston 5, a brake actuation spring 8 is engaged with the piston 5, and a microcontroller is connected to the cover removably attached to the caliper 3, which faces the switch operation part of the piston rod 6. In a disc brake pad wear detection device to which a switch 9 is attached, a mounting bolt 11 inserted around an end cover 10 to which a microswitch 9 is attached is screwed into a surrounding cover 12 fixed to the caliper 3. A pad wear detection and adjustment device for a disc brake, characterized in that a gap is provided between the end of the peripheral cover 12 and the flange of the end cover 11.
