Abstract
A disc brake having an anchor member with first and second grooves that receive first and second ears on a backing plate to align a friction surface of a friction pad with a rotor. A first slipper spring is secured to the anchor and located between the first groove and the first ear. A second slipper spring is secured to the anchor and located between the second groove and the second ear. The first and second ears correspondingly slide on the first and second slipper springs in response to an input force being applied to move the backing plate toward a rotor to bring the friction surface into engagement with the rotor during a brake application. Each of the first and second slipper springs is characterized by a base with parallel top and bottom side walls that extends therefrom. The top side wall has a lip thereon that engages the anchor to position the base in a groove. The bottom side wall has an arm that extends therefrom along a plane that forms an angle of less than 90 degrees with respect to the base and second wall. The arm tangentially engages a single point contact on the backing plate to resiliently urge the ears away from the grooves to define a first gap between the ear…
