ABSTRACT:
A disc brake is provided with a warning device or sensor made of a springy material. The sensor is mounted within an space between a friction disc and pad assembly and a yoke, and has a tongue portion formed with a section adapted to rub on a rotating disc at an area disposed outside of the contact surface. When a friction pad is worn out to a predetermined thickness, the section rubs on the disc, emitting an audible warning sound to alert the driver that something is wrong and he should take appropriate action.
