Abstract:
A brake shoe brakes a drum rotor by being pressed against the inner circumferential surface of the drum rotor. A friction material in the brake shoe comprises a first lining material, a second lining material, and a third lining material. The arcuate friction material faces the inner circumferential surface of the drum rotor, and the first lining material is one end section of said friction material in the direction of rotation of the drum rotor. The second lining material is the other end section of the friction material in the direction of rotation of the drum rotor. The third lining material is positioned between the one end section and the other end section in the direction of rotation of the drum rotor and is made so as to wear faster than the first lining material and the second lining material.
