ABSTRACT:
The objective of the claimed invention is to provide a drum brake device that enables an accurate determination of the degree of wear in the brake lining with an external visual examination. A colored strip 24, that visually confirms the amount of wear in the brake lining, is formed on one side face 23a of the brake lining 23 contained in brake shoe 20, and code 25 is superimposed on said colored strip. An inspection hole 14, bored in backplate 10 in a position facing the colored strip 24 and code 25 formed on lining 23, is used to visually ascertain the amount of wear in lining 23 and to check for the assembly of foreign parts in the brake shoe 20.
