1. A device comprising: a. a pair of opposing legs;b. a bridge between and connecting the pair of legs;c. a pair of retraction spring arms attached to the outside of each of the legs; the retraction spring arms each comprising: i. a guide support tab connected to each of the pair of retraction spring arms;wherein the retraction spring arms assist in retracting a pair of brake pads, and the guide support tabs guide the retraction spring arms during movement;wherein the guide support tab contacts a projection on the pair of opposing legs so that the arms do not rotate during brake wear, brake apply, brake retraction, or a combination thereof;wherein the guide support tabs each include a dimple so that the guide support tabs maintain contact with the projection on the pair of opposing legs regardless of orientation of the guide support tabs to the projection. 2. The device of claim 1, wherein the guide support tabs slide; along a portion of a face of a projection, on the pair of opposing legs, during brake wear, brake apply, brake retraction, or a combination thereof. 3. The device of claim 1, wherein the retraction spring arms each include a retraction limb, and the retraction limb remains straight during a brake apply. 4. The device of claim 3, wherein the retraction spring arms each include a connection limb and a pull-back limb that are connected by a pull-back curve, the pull-back curve being stiff so that the pullback curve creates a flexible resistance that allows for the respective retraction spring arm to be offset away from a rotor and a rotor gap. 5. The device of claim 3, wherein the retraction spring arms each include a pull-back limb and an arcuate limb are connected together by an arcuate curve, the arcuate curve being stiff enough so that the angle between the pull-back limb and the arcuate limb remain substantially the same as a force is applied to the retraction spring arm. 6. The device of claim 3, wherein the retraction spring arms each include an arcuate limb and a retraction limb that are connected by a retraction curve, the retraction curve changing angle during a brake apply so that a majority of the force applied during a brake apply is stored in the retraction curve, the arcuate limb, or both so that the stored energy will create a force in a retract direction when the brake apply is complete. 7. The device of claim 3, wherein the retraction spring arms each include a connection limb, a pull-back limb, and a pull-back curve, the pull-back curve forming an angle from about 45 degrees to about 115 degrees between the connection limb and the pull-back limb. 8. The device of claim 3, wherein the retraction spring arms each include a pull-back limb, an arcuate limb, and arcuate cure, the arcuate curve forming an angle from about 30 degrees to about 105 degrees between the pull-back limb and the arcuate limb. 9. The device of claim 3, wherein the retraction spring arms each include an arcuate limb, a retraction limb, and a retraction curve, the retraction curve forming an angle from about 105 degrees to about 135 degrees between the arcuate limb and the retraction limb. 10. A device comprising: a. a pair of opposing legs;b. a bridge between and connecting the pair of legs;c. a pair of retraction spring arms attached to the outside of each of the legs; the retraction spring arms each comprising: i. a guide support tab connected to each of the pair of retraction spring arms;wherein the retraction spring arms assist in retracting a pair of brake pads, and the guide support tabs guide the retraction spring arms during movement;wherein the guide support tab contacts a projection on the pair of opposing legs so that the arms do not rotate during brake wear, brake apply, brake retraction, or a combination thereof;wherein each of the retraction spring arms include a retraction limb and the guide support tabs are substantially perpendicular to the retraction limb of each of the retraction saps mg arms. 11. The device of claim 10, further including a locator on the outside of each of the pair of opposing legs, the locator being juxtaposed to the projection. 12. The device of claim 10, wherein each of the pair of opposing, legs include a locator and the locators are box shaped. 13. The device of claim 10, wherein the guide support tabs slide along: a portion of a face of the projection, on the pair of opposing legs, during brake wear, brake apply, brake retraction, or a combination thereof. 14. The device of claim 10, wherein the retraction spring arms each include a retraction limb, and the retraction limb remains straight during a brake apply. 15. A device comprising: a. a pair of opposing legs;b. a bridge between and connecting the pair of legs;c. a pair of retraction spring arms attached to the outside of each of the legs; the retraction spring arms each comprising: i. a guide support tab connected to each of the pair of retraction spring arms;wherein the retraction spring arms assist in retracting a pair of brake pads, and the guide support tabs guide the retraction spring arms during movement;wherein the pair of retraction spring arms are comprised of:a) a connection limb, the connection limb extends away from and substantially perpendicular to each of the legs;b) a pull-back limb connected to the connection limb;the pull-back limb curves perpendicular to the connection limb towards the opposing leg and is substantially parallel to each of the legs without extending into a rotor gap located under the bridge;c) an arcuate limb connected to the pull-back limb;the arcuate limb being substantially perpendicular to the pull-back limb and the legs;the arcuate limb curves out and away from the respective legs; andthe arcuate limb curves down and away from the pull-back limb;d) a retraction limb on the side of the arcuate limb opposite the pull-back limb,the retraction limb turning at an angle away from the rotor gap such that a small dimensional portion is facing respective leg; ande) a distal end limb on a side of the retraction limb opposite the arcuate limb,the distal end limb turning at an angle so that the a face of the distal end limb is substantially parallel to the rotor gap, a brake pad, or both. 16. The device of claim 15, wherein the guide support tab contacts a projection on the pair of opposing legs so that the arms do not rotate during brake wear, brake apply, brake retraction, or a combination thereof. 17. A device comprising: a. a pair of opposing legs;b. a bridge between and connecting the pair of legs;c. a pair of retraction spring arms attached to the outside of each of the legs; the retraction spring arms each comprising:i. a guide support tab connected to each of the pair of retraction spring arms;wherein the retraction spring arms assist in retracting a pair of brake pads, and the guide support tabs guide the retraction spring arms during movement;wherein the retraction spring arms each include a retraction limb that remains straight during a brake apply, and a distal end limb that are connected to the retraction limb by a distal end curve, the distal end curve forming an angle so that a face of the distal end limb is substantially parallel to a rotor gap, a face of a brake pad, or both. 18. The device of claim 17, wherein each of the pair of opposing legs include a locator and the locators extend away from the leg portion and curve backwards upon itself. 19. The device of claim 17, wherein the guide support tabs slide along: a portion of a face of a projection, on the pair of opposing legs, during brake wear, brake apply, brake retraction, or a combination thereof. 20. The device of 17, wherein the guide support to contacts a projection on the pair of opposing legs so that the arms do not rotate during brake wear, brake apply, brake retraction, or a combination thereof. 21. A device comprising: a. a pair of opposing legs;b. a bridge between and connecting the pair of legs;c. a pair of retraction spring arms attached to the outside of each of the legs: the retraction spring arms each comprising: i. a guide support to connected to each of the pair of retraction spring arms;wherein the retraction spring arms assist in retracting a pair of brake pads, and the guide support tabs guide the retraction spring arms during movement:wherein the retraction spring arms each include a retraction limb, and the retraction limb remains straight during a brake apply;wherein the retraction spring arms each include a distal end limb and a distal end curve, the distal end curve forming an angle from about 105 degrees to about 150 degrees between the retraction limb and the distal end limb. 22.
