The present invention relates to a cable-operated bicycle disc brake that operates by the tension of an inner cable connected to a brake lever. The cable-operated bicycle disc brake of the present invention comprises a rotating disc, a brake pad, a caliper body that movably supports the brake pad, an operating arm in which the inner cable is fixed and which rotates by the tension of the inner cable, a conversion mechanism that converts the rotation of the operating arm into movement of the brake pad toward the rotating disc, and an automatic separation compensation mechanism that updates the return reference position of the brake pad from the released state toward the rotating disc. When the operating stroke of the operating arm, which increases with wear of the brake pad, exceeds the reference stroke, the automatic separation compensation mechanism updates the return reference position while maintaining the fixed position of the inner cable relative to the operating arm, thereby maintaining the separation distance between the rotating disc and the brake pad within a target separation range. Accordingly, the user does not have to repeat the operation of pulling and fixing the inner cable again in response to brake pad wear, and unnecessary position updates are suppressed within the normal operating range, thereby preventing pad dragging and overcompensation.
