Resilient structure for disc brake friction pad

摘要

Herein disclosed is a resilient structure for use in a disc brake of the type including an electric wire having its looped end extending in the brake lining from the rear side thereof with a predetermined distance, and detecting means feeding an electric current to the electric wire for detecting disconnection at the looped end to indicate that the brake lining is worn out to exceed the working limit of the disc brake. The resilient structure includes a guide member pressor extending circumferentially of the brake disc and resiliently engaged with the guide member of the disc brake for applying a thrust to the latter, and a resilient arm extending from the guide member pressor and engaged with the electric wire for applying a tension to the same to ensure said disconnection. The resilient structure may be made of a simple spring wire, and biases the friction pad so as to prevent undesirable noises which might otherwise be produced at the frictional engagement between the friction pad and the brake disc.
