Abstract
A brake caliper includes a caliper housing having a first cavity. A piston is reciprocally moveable in the cavity. The piston is configured with a non-circular outer periphery defining a cross-sectional area orthogonal to the first axis. A portion of the outer periphery may be defined by a linear portion. The outer periphery may be disposed within an outer periphery of a brake pad coupled to the piston when the outer periphery of the piston is superimposed on a cross-sectional area of the brake pad.
Claims20
A brake caliper comprising:
- a caliper housing comprising a cavity;
- and
- a piston movably disposed in the cavity, wherein the piston is reciprocally movable in the cavity along a first axis, and wherein the piston comprises a non-circular outer periphery defining a cross-sectional area orthogonal to the first axis, wherein the cross-sectional area comprises a major axis having a first length and a minor axis having a second length, wherein the major axis is orthogonal to the minor axis, and wherein a power elongation ratio of the first length to the second length is greater than or equal to 1.5.
A brake caliper comprising:
- a caliper housing comprising a cavity;
- a piston movably disposed in the cavity, wherein the piston is reciprocally movable in the cavity along a first axis, and wherein the piston comprises a non-circular first outer periphery defining a first cross-sectional area orthogonal to the first axis;
- and
- a brake pad coupled to the piston, wherein the brake pad comprises a second outer periphery defining a second cross-sectional area orthogonal to the first axis, wherein the outer periphery of the piston is disposed within the outer periphery of the brake pad when the outer periphery of the piston is superimposed on the cross-sectional area of the brake pad along the first axis.
