Abstract:
A disc brake having an anchor member with first and second grooves that correspondingly receive first and second ears on a backing plate to align a friction surface on a friction pad with a rotor, a first slipper spring that is secured to said anchor and located between said first groove and said first ear and a second slipper spring that is secured to said anchor and located between said second groove and said second ear, said first and second ears correspondingly sliding in said first and second slipper springs in response to an input force being applied to move said backing plate toward a rotor and said friction surface into engagement with said rotor to effect a brake application, each of said first and second slipper springs being characterized by a base having parallel first and second side walls that extends therefrom, said first wall having a lip thereon engages said anchor to position said base in one of said first and second grooves, said second wall having an arm that extends from a point along a plane that forms an angle of less than 90 degrees with respect to said base and said second wall, said arm tangentially engaging a single point of contact on said backing plate to resiliently urge said ear both radially and tangentially simultaneously away from said groove to define a first gap between said ear and said base and to resiliently urge said ear into engagement with said first wall to define a second gap between said ear and said second wall.
