Abstract

PURPOSE: To enable an alarm operation for the brake to be performed by the warning device in the vicinity of a driver's seat in the vehicle when brake linings reach the limited wear of use, by such means that the detecting unit rotated by a contact with friction surfaces of the rotating drum is arranged in a protrusively installed condition from surfaces of the brake shoe unit.
CONSTITUTION: To the drum brake is installed a detecting part 10 constructed by supporting a roller 4 that works as the detecting unit to a body 2 through a rotary shaft 5. Here on the rear face of a shoe 12a on the front face of which a lining 11a is pasted, the body 2 is fixed by the method of weling and the like to permit the roller 4 to be protrusively positioned from the hole provided in the shoe 12a to a critical point of use of the lining 11a. Now if the lining 11a is worn out reaching the critical degree of use due to the long time operation, the level of surface of the lining 11a comes to be of the same height as that of circumferential face of the roller 4. This causes the roller 4 to be rotated by the turning effect of a drum 14a resulting in the constitution of utilizing the turning effect of the roller 4 to perform the operation of every kind of the warning device.
