The front brake shoes of the Jetta, for example, are 14 mm thick, while the replacement limit is 7 mm, which includes over 3 mm of iron liner and nearly 4 mm of friction material. Some vehicles are equipped with brake shoes alarm function, once reached the wear limit, the instrument will alarm to replace the shoes. If the shoes reach the limit of use, they must be replaced.
