Abstract
An easily insertable and removable brake pad abrasion detector is provided by forming a recess in the rear surface of the pad, a hole in the pad backing plate communicating with the recess, a sleeve in the hole having inwardly projecting one-way pawls and a probe having a circumferential shoulder engaged by the pawls when inserted. The small diameter part of the probe may have an elliptical cross-section so that the pawls may be disengaged by merely turning the probe.
Claims10
A structure for mounting an electrical brake pad abrasion detector, of the type in which a through hole is formed in a backing plate in such a manner as to communicate with a blind hole formed in a brake pad, wherein the improvement comprises:
- a cylindrical holding member fixedly secured in said through hole, said holding member having at least one no-return pawl provided on the inner periphery thereof, said pawl having an end disposed within said cylindrical holding member;
- a substantially cylindrical probe having head and leg sections meeting to form a shoulder at the intermediate portion of said probe, said probe being inserted into said holding member so as to allow the end of said at least one no-return pawl to engage with said shoulder to thereby hold said probe;
- and
- the diameter of a portion of said holding member, extending from the vicinity of the end of said at least one no-return pawl to one end of said holding member adjacent said head section, being made larger than that of a remaining portion thereof.
