The invention discloses a bicycle brake lining shoe. The bicycle brake lining shoe comprises a steel piece (1) and a friction plate (2), wherein the steel piece (1) is of an n-shaped structure and provided with a reinforcing device, the reinforcing device comprises at least four bosses (3) which are symmetrically arranged, the area of the portions, inserted into the friction plate, of the bosses is enlarged, and the bosses are evenly distributed. From the mechanics perspective, by means of arrangement at the angle, shearing force of the brake lining shoe is enhanced in both the longitudinal direction and the transverse direction, and shearing strength of the brake lining shoe is enhanced; the thickness of high-temperature glue is controlled to range from 0.03 mm to 0.15 mm in a gluing process, and gluing connection strength is enhanced. The friction plate (2) is composed of friction materials and adhesion agents, the friction materials are less-metal materials, so that the friction layer and a steel board layer have higher adhesive force and tenacity, the shearing strength of the brake lining shoe is further enhanced, and the gluing joint can bear the maximum load parallel to the gluing connection surface per unit area.
