Stepped piston for disk brake with oversized footing

A piston configured for use in a disk brake system, the piston comprising:

• a body;
• and
• a footing;
• the body having
• a lateral wall encircling an internal space within the piston;
• and
• an end wall at an end of the piston, the end wall having a central portion extending outward from the end wall;
• the footing positioned adjacent the end wall distal the interior space, and having a recess that receives the central portion;
• wherein during operation of the disk brake system, the footing is located between a portion of the end wall and a brake pad, and the footing extends along the brake pad, and is configured to exert force on the brake pad during actuation of the disk brake system;
• and
• the footing having a face configured to contact the brake pad, the face having a length and a width, wherein the length is longer than an outside width of the body, and the length is greater than the width, and/or the face having a cross-sectional area normal to a direction of travel of the piston that is larger than a cross-sectional area of the piston that is normal to the direction of travel of the piston;
• and
• first and second ends of the footing located at the respective first and second ends of the length have less deflection than a midpoint of the footing corresponding to a central axis of the piston.
