Two snubber brakes sit on a KC-135 Stratotanker aircraft at MacDill Air Force Base, Fla., Aug. 12, 2014. The KC-135 uses a snubber brake system consisting of two brake linings attached to two spring arms that contact the nose landing gear tires after gear retraction to eliminate noise and vibration.
