Abstract
A brake pad retraction spring that includes a coil, first and second biasing arms, and first and second biasing tips. The first and second biasing arms may extend from the center coil. The first and second biasing tips may extend from ends of the first and second biasing arms, respectively.
Claims22
A brake pad retraction spring comprising:
- a first biasing arm that extends along a central axis of the first biasing arm when the brake pad retraction spring is in a free state;
- a second biasing arm that extends along a central axis of the second biasing arm when the brake pad retraction spring is in the free state;
- a first biasing tip that extends along a first central axis from an end of the first biasing arm when the brake pad retraction spring is in the free state, wherein the first central axis intersects the central axis of the first biasing arm
- a second biasing tip that extends along a second central axis from an end of the second biasing arm when the brake pad retraction spring is in the free state, wherein the second central axis intersects the central axis of the second biasing arm;
- wherein the central axis of the first biasing arm and the central axis of the second biasing arm are disposed on opposite sides of a center plane and do not intersect the center plane when the brake pad retraction spring is in the free state;
- wherein the first biasing tip and the second biasing tip are disposed on opposite sides of the center plane and do not intersect the center plane when the brake pad retraction spring is in the free state;
- wherein the first central axis extends at an oblique angle from the central axis of the first biasing arm such that the first central axis and the first biasing tip extend toward the center plane when the brake pad retraction spring is in the free state;
- and
- wherein the second central axis extends at an oblique angle from the central axis of the second biasing arm such that the second central axis and the second biasing tip extend away from the center plane when the brake pad retraction spring is in the free state.

A brake pad retraction spring comprising:
- a coil that extends around a center axis;
- first and second biasing arms that extend from the coil;
- a first biasing tip that extends along a first central axis at an angle from an end of the first biasing arm;
- and
- a second biasing tip that extends along a second central axis at an angle from an end of the second biasing arm, wherein the first biasing tip and the second biasing tip are disposed on opposite sides of a center plane and the center plane does not intersect the first and second biasing tips when the brake pad retraction spring is in a free state, the center plane intersecting the coil and the center axis.

A brake pad retraction spring comprising:
- a coil that extends around a center axis;
- a first biasing arm that extends from the coil;
- a first biasing tip that extends along a first central axis from an end of the first biasing arm toward a center plane that intersects the coil and is disposed substantially perpendicular to the center axis;
- a second biasing arm that extends from the coil;
- and
- a second biasing tip that extends along a second central axis from an end of the second biasing arm away from the center plane, wherein the center plane does not intersect the first and second biasing tips when the brake pad retraction spring is in a free state.
