Claims

[Scope of utility model registration request]

A disc that rotates together with the wheel, a mounting that is fixed to the vehicle on one side of the disc, and a pair of friction pads that are arranged on both sides of the disc and each have a lining made of short metal fiber or other resin. an actuator that is slidably supported by the mounting through at least one pin parallel to the axis of the disk along the axis of the disk, and that presses one friction pad on one side of the disk against one side of the disk; and a caliper whose actuating reaction force of the actuator presses the other friction pad against the other side of the disk, and a caliper located between the mounting and the caliper to protect the sliding portion between the pin and the mounting or the caliper. The rubber boot, the attachment part for fixing the friction pad to the side end of the back plate, and the lining of the friction pad extending toward the side of the disk through the side of the back plate have been worn down to the service limit. A friction pad wear-out alarm member made of a plate material, which has a vibrating piece that contacts the side surface of the disk at the tip and vibrates to generate an alarm sound, and a spring acting part that presses this vibrating piece against the end face of the back plate with a predetermined force. In the disc brake for a vehicle equipped with a friction pad wear-out warning member, the friction pad wear-out warning member is attached to both ends of a back plate of a friction pad located on the same side as the boot with respect to the disc; The friction pad wear-out warning member is integrally formed with a fire prevention wall part that blocks flames generated on the inside of the friction pad in the radial direction of the disk and directed toward the boot from reaching the boot during braking.
