VEHICLE DISK BRAKE LINING WEAR

摘要

An abrasion detecting apparatus for a friction member comprises a detecting switch having facing electric contacts constituted on the one hand as a rotating member such as the brake disk and on the other hand a lead wire embedded in a friction member such as a brake pad facing the rotating member. The switch is interposed in a circuit having an indicating device such as a lamp connected to an electric source. The portion of the lead wire embedded in the friction member is covered over the entire surface thereof with an insulating layer such as an insulating tube.
