In order to reduce a size, weight, and power consumption of a braking apparatus by using a lining structure and a rotor surface shape which provide a high friction coefficient between a brake lining and a rotor and through a method of manufacturing a lining, provided is a braking apparatus, including: a rotary body rotatable about a rotation shaft; a fixed core including a coil built therein and provided on an inner side of the rotary body; a movable core, which is attracted to the fixed core through excitation of the coil to come into contact with the fixed core and is subj ected to a repelling force by a spring provided to the fixed core; and a brake lining being a formed product which is capable of sliding against concave and convex portions of the rotary body, contains fibers arranged in a direction approximately perpendicular to a sliding direction, and is hardened by a blended material, the brake lining being provided to the movable core. Further, the lining is manufactured in such a manner that the fibers are mixed with a friction material when being twisted so as to produce a twisted strand mixed with the friction material, and a plurality of the twisted strands are further twisted so as to produce a strand having a predetermined diameter, which is finally heated and pressurized. |
