Abstract
The invention relates to a braking shoe which comprises a liner and a friction piece. The liner and the friction piece are fixed together. The friction piece is provided with a front face and a back face which are opposite. The back face of the friction piece is in contact with the liner. At least two coloring blocks are arranged in the friction piece. When the braking shoe is arranged on a vehicle, the distances between different coloring blocks and the center line of a braking disc are different. The coloring blocks have the color in contrast to the color of the braking disc. The end faces, close to the front face, of the coloring blocks are effect faces. The distances between the effect faces of different coloring blocks and the front face are different. The effect face, farthest from the front face corresponds to the wear limit of the friction piece. When the braking disc is in contact with the effect face, the friction piece reaches the wear limit. Under the premise that manufacturing cost is hardly increased, a car driver can observe the wear situation of the braking shoe clearly; the fact that the car driver can accurately judge whether the braking shoe needs to be replaced is guaranteed; braking failure accidents caused by overusing of the braking shoe can be effectively avoided.
