    • A brake lining wear indicating device is inserted into an aperture (7) of a brake lining carrier (8) of a drum or disc brake from the side facing away from the brake lining (1) and secured in the aperture. The indicating device includes a slotted (16) sleeve shaped holder (2) and a contact member (3) inserted into and axially secured to the holder and has an electrical conductor (4) therein. In order that the indicating device can be fitted into brake lining carriers of different thickness, holder (2) has on its side facing away from the brake lining (1) a frustonconical section (13) having an outwardly narrowing inner frustoconical area (14) and several axially extending slots (16). When contact member (3) is inserted into holder (2), frustoconical part (13) of the holder is forcibly radially expanded and wedged into aperture (7) of brake lining carrier (8).
    • 制动衬片磨损指示装置从背离制动衬片(1)的一侧插入到鼓或盘式制动器的制动衬片载体(8)的孔(7)中并固定在孔中。 指示装置包括插槽(16)套筒形保持器(2)和插入并轴向固定到保持器的接触构件(3),并且在其中具有电导体(4)。 为了使指示装置能够装配到不同厚度的制动衬片载体中,保持器(2)的侧面背向制动衬片(1)具有向外变窄的内截头圆锥形区域(14)的截头圆锥体部分(13) 和多个轴向延伸的槽(16)。 当接触构件(3)插入到保持器(2)中时,保持器的截头圆锥形部分(13)被强制地径向膨胀并楔入制动衬片载体(8)的孔(7)中。
