Friction Pad Carrier for a Disc Brake

A disc brake for a vehicle, comprising:

• a friction pad carrier comprising
• a frame defining a central aperture configured to receive an arcuate portion of a rotor that is configured for rotation about a rotational axis, the frame configured for mounting first and second friction pads on opposite sides of the rotor and further defining
• a first lug proximate one end of the frame and defining a first fastener bore, the first fastener bore configured for alignment with a corresponding first fastener bore in an anchor plate mounted on an axle of the vehicle and configured to receive a first fastener for coupling the frame to the anchor plate at a first interface disposed within a plane;
• and,
• a second lug proximate another end of the frame and defining a second fastener bore, the second fastener bore configured for alignment with a corresponding second fastener bore in the anchor plate and configured to receive a second fastener for coupling the frame to the anchor plate at a second interface disposed within the plane;
• wherein the first fastener and the second fastener permit an amount of surge movement between the frame and the anchor plate within the plane in a direction parallel to the rotational axis, an amount of sway movement between the frame and the anchor plate within the plane in a direction perpendicular to the surge movement and an amount of yaw movement about an axis perpendicular to the plane and
• wherein the first lug further defines a first alignment pin bore configured for alignment with a corresponding first alignment pin bore in the anchor plate and configured to receive a first alignment pin inhibiting the amount of surge movement and the amount of sway movement and one of the first lug and the second lug defines a second alignment pin bore configured for alignment with a corresponding second alignment pin bore in the anchor plate and configured to receive a second alignment inhibiting the amount of yaw movement;
• and,
• a caliper coupled to the friction pad carrier and configured for movement relative to the friction pad carrier to urge the first friction pad and the second friction pad into engagement with the rotor.
