The present disclosure provides systems for mitigating brake vibration. In various embodiments, a brake force distribution arrangement may comprise: a member in operable communication with an actuator having at least two contact surfaces such that as one of the at least two contact surfaces moves in a direction of actuation of the actuator the other moves in a direction opposite to the direction of actuation of the actuator.

1. A brake force distribution arrangement comprising: a pressure plate;a member in operable communication with an actuator through an attachment feature, the member configured to pivot about the attachment feature in two planes, the member having at least two contact surfaces, each contact surface comprising a boss extending from the member and configured to contact the pressure plate, such that as one of the at least two contact surfaces moves in a direction of actuation of the actuator the other moves in a direction opposite to the direction of actuation of the actuator as the member pivots,wherein the at least two contact surfaces are circumferentially spaced apart from each other. 2. The brake force distribution arrangement of claim 1, wherein the member extends from a first end to a second end. 3. The brake force distribution arrangement of claim 1, wherein the first contact surface is located proximate the first end of the member and the second contact surface is located proximate the second end of the member. 4. The brake force distribution arrangement of claim 1, wherein the attachment feature is configured to be coupled to a ball screw. 5. The brake force distribution arrangement of claim 1, wherein the attachment feature is located closer to the first end than the second end. 6. A brake arrangement comprising: an actuator plate;an actuator coupled to the actuator plate, the actuator including a ball screw extending from the actuator; anda member including a first contact surface extending from the member in close proximity to a first end of the member and comprising a first boss, a second contact surface extending from the member in close proximity to a second end of the member and comprising a second boss, the first and second boss configured to contact a pressure plate, and an attachment feature located between the first end and the second end about which the member is configured to pivot in two planes, the member coupled to the ball screw via the attachment feature,wherein the first contact surface is circumferentially spaced apart from the second contact surface. 7. The brake arrangement of claim 6, wherein the first boss and the second boss are configured to contact the pressure plate to apply a force to the brake arrangement. 8. The brake arrangement of claim 6, wherein the first boss and the second boss comprise at least one of a circular, rectangular, or elliptical geometry. 9. The brake arrangement of claim 6, wherein the member comprises a supporting plate defining a circular arc. 10. The brake arrangement of claim 6, wherein the member comprises at least one of a carbon/carbon material or a metal alloy, metal matrix composite (MMC), a medium carbon steel, a high carbon steel, or a composite ceramic. 11. The brake arrangement of claim 6, wherein the member comprises a flexural plate. 12. The brake arrangement of claim 6, wherein the member is configured to evenly distribute the first contact surface and the second contact surface about the actuator plate. 13. A member for a brake arrangement comprising: a first contact surface extending from a first end of the member and comprising a first boss;a second contact surface extending from a second end of the member and comprising a second boss, the first and second boss configured to contact a pressure plate, the member extending from the first end to the second end and comprising a circular arc, wherein an arc length of the member is between 5% and 35% of a circumference of an adjacent pressure plate and an aspect ratio of the plate is between 2 and 20; andan attachment feature located between the first end and the second end of the member, wherein the member is configured to pivot about the attachment feature in two planes, and the attachment feature is configured to be coupled to a ball screw,wherein the first contact surface is circumferentially spaced apart from the second contact surface. 14. The member for a brake arrangement of claim 13, wherein the arc length of the member is between 10% and 25% of the circumference of the adjacent pressure plate. 15. The member for a brake arrangement of claim 13, wherein a depth of the first boss and the second boss is between 10% and 200% of a depth of the plate. 16. The member for a brake arrangement of claim 13, wherein a width of the first boss and the second boss is between 90% and 110% of a width of the member. 17. A brake force distribution arrangement comprising: a pressure plate;a member in operable communication with an actuator through an attachment feature, the member configured to pivot about the attachment feature in two planes, the member having at least two contact surfaces, each contact surface comprising a boss extending from the member and configured to contact the pressure plate, such that as one of the at least two contact surfaces moves in a direction of actuation of the actuator the other moves in a direction opposite to the direction of actuation of the actuator as the member pivots,wherein the attachment feature is located closer to the first end than the second end.
