Wear detection probe with a wire falling out prevention member

摘要

A probe for detecting wear of a lining such as a brake pad in automobiles includes a holder having two insertion apertures and a notch. An electrically conducting wire is inserted through the insertion apertures of the holder. Portions of the wire positioned in the notch are secured to a fallout preventing member. Upon the progressive wear of the lining, a U-shaped portion of the wire is severed by a rotor of the brake system. The fallout preventing member prevents the wire from falling out of the holder once the wire has been severed. The portions of the wire remaining after the wire has been severed by the rotor can thus be prevented from twining around the rotor or the like.
