Wear indicator for the friction lining of an automobile, in particular of a brake lining

摘要

the witness wear (10) includes a body (12) to be encliquetu00e9 on a friction lining carrier with the aid of a ratchet body (18). the body (12) includes a first orifice (24) forming a pump body housing (22) for the detection of wear and tear.the witness wear (10) includes a body (30) for maintaining the wear detection body (22) in the first orifice (24), which is separate from the main body (12), the body of the ratchet (18) together with the body (30) so as to maintain the pin in the body (12).the support body (30) includes an element of plot, the wear detection body (22) forming a substantially planar surrounding the open loop forming element wire.
