Abstract
A spring clip located in a rail of an anchor of a disc brake to hold a carrier for a friction pad and provide a surface on which a projection on the carrier slides during movement of a the carrier toward a rotor by an input force to effect a brake application. The spring clip is characterized by a base having a surface thereon that substantially matches and covers the rail. A tab that extends from the base engages the anchor to fix the position of the base in the rail with respect to the rotor. An arm that extends inward from the base in plane perpendicular to the base has a lip on the end thereof that extends in a plane parallel with the rail. The projection on the carrier engages the arm whenever wear reduces a thickness of the friction pad to a predetermined thickness such that the projection thereafter engages the arm to bring the lip into engagement with the rotor whenever the first friction pad engages the rotor during a brake application. The lip on engagement with the rotor causes the arm to vibrate and thereby create an audible sound designed to alert an operator that optimum braking might thereafter be impaired with continued use of the friction pad.
