Abstract
A disc brake caliper of a human-powered vehicle includes a caliper body including a first hole and a second hole, a first piston movably provided in the first hole, and a second piston movably provided in the second hole. The first piston has a first outer diameter. The second piston has a second outer diameter. A ratio of the first outer diameter to the second outer diameter is greater than or equal to 1.15.
Claims16
A disc brake caliper of a human-powered vehicle, comprising:
- a caliper body including:
- a first interior wall;
- a second interior wall;
- a first hole;
- a second hole provided on an upstream side of the first hole in a driving rotational direction of a disc brake rotor;
- a pad space in which a brake pad is to be at least partially provided, the pad space being defined between the first interior wall and the second interior wall in an arrangement direction, the pad space having a length defined between the first interior wall and the second interior wall in the arrangement direction;
- a first piston having a first center axis and movably provided in the first hole along the first center axis;
- a second piston having a second center axis and movably provided in the second hole along the second center axis;
- a first distance defined between the first center axis and a reference center plane in the arrangement direction, the reference center plane being perpendicular to the arrangement direction and defined to bisect the length of the pad space in the arrangement direction;
- a second distance defined between the second center axis and the reference center plane in the arrangement direction;
- and
- the first distance being shorter than the second distance.
A disc brake caliper of a human-powered vehicle, comprising:
- a caliper body including:
- a first interior wall;
- a second interior wall;
- a hole;
- a pad space in which a brake pad is to be at least partially provided, the pad space being defined between the first interior wall and the second interior wall in an arrangement direction, the first interior wall and the second interior wall being spaced apart in the arrangement direction, the second interior wall having a proximal surface and a distal surface, the proximal surface being at least partially provided farther from the first interior wall than the distal surface in the arrangement direction;
- and
- a reference wall plane defined on the distal surface;
- and
- a piston having a center axis and movably provided in the hole along the center axis, the hole being partially provided farther from the first interior wall than the reference wall plane in the arrangement direction as viewed along the center axis.
A disc brake caliper of a human-powered vehicle, comprising:
- a caliper body including a first hole and a second hole;
- a first piston movably provided in the first hole, the first piston having a first outer diameter;
- a second piston movably provided in the second hole, the second piston having a second outer diameter;
- and
- a ratio of the first outer diameter to the second outer diameter being greater than or equal to 1.15.
