Abstract
A friction pad for a disk brake is designed so that a wear sensor can be firmly secured to the friction pad. A circular cylindrical projection is formed on a backing plate of the friction pad by extrusion so that a wear sensor adapted to sound an alarm by coming in contact with a disk is fitted onto the projection and secured to the backing plate by caulking the projection. The projection is so deformed that the diameter d.sub.1 and height h.sub.1 of a resulting radially enlarged portion satisfy the relationship of (d.sub.1 -3.4).times.h.sub.1 .gtoreq.2.5, thereby preventing rotation of the wear sensor and rising of the enlarged portion.
