Abstract
PURPOSE: To permit an alarm for wear of a brake lining to be generated whether the brake is been operated or not by forcing an alarming member to contact to the disc all the time when the lining has been weared to its given part.
CONSTITUTION: When a lining 8 has been weared by a part of given thickness G, a cavity 8a provided at a given part in the lining 8 is opened. Consequently, a free end 11d of an elastic member 11 attached to the lower surface of a pad plate 7 is released from restraint, and the elastic member 11 is restored in the direction C of energization forcing the free end 11d to contact to a braking surface 9a of a disc 9, causing a grinding sound or alarm to be generated as the disc 9 rotates. When the brake is operated the free end 11d is contacted to the braking surface 9a more strongly then when the brake is not operated. Therefore, a clear alarm which is never be mistaken for braking or other noises is generated.
