A wear indicating friction disc assembly includes at least two friction discs and may include a plurality of clamping assemblies positioned around a circumference of the friction discs to clamp at least two of the friction discs together. At least one of the clamping assemblies may include a wear indicating washer with a wear indicating portion extending into a portion of one at least one of the friction discs. A height of the wear indicating portion is set to engage the opposing friction member at a predetermined wear level of the friction disc assembly and to emit a detectable signal upon sliding engagement with the opposing friction member.
