PAD WEAR DETECTOR FOR A DISC BRAKE

摘要

The invention relates to a pad wear detector (10) for a disc brake with an adjusting device (3, 6) in which the brake shoe gap is kept substantially constant by means of at least one axially acting adjuster (1) and which is coupled to the pad wear detector (10) in such a way that the latter detects the relative axial position of the adjuster (1) and derives a corresponding wear signal therefrom. To facilitate maintenance, the invention proposes that the pad wear detector (10) be arranged in a separate housing (11) releasably secured to the disc brake and actuated by the adjuster (3, 6) via a releasable coupling component (11, 22).
