A spring clip 100,200 located in a rail 31,33 of an anchor 12 of a disc brake 10 to hold a carrier 34,38 for a friction pad 30,32 and provide a surface on which a projection 34a,38a,34b,38b on the carrier 34,38 slides during brake application. The spring clip 100,200 is characterized by a base 314,316 having a surface thereon that substantially matches and covers the rail 31,33. A tab 320,322 that extends from the base 314,316 engages the anchor 12 to fix the position of the base 314,316 in the rail 31,33. An arm 324,326 that extends inward in plane perpendicular to the base 314,316 has a lip 328,330 on the end thereof that extends in a plane parallel with the rail 31,33. The projection 34a,38a,34b,38b on the carrier 34,38 engages the arm 324,326 whenever wear reduces a thickness of the friction pad 30,32 to a predetermined thickness to bring the lip 328, 330 into engagement with the rotor 42, causing the arm 324,326 to vibrate and thereby creating an audible sound to alert an operator that optimum braking might be impaired.
