1. 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.
