Word Origin & History

brake 
c.1440, from O.Du. braeke "flax brake," from breken "to break." The word was applied to many crushing implements, and the ring through the nose of a draught ox. It was infl. in sense by O.Fr. brac, a form of bras "an arm," thus "a lever or handle," which was being used in Eng. from 1380, and applied to "a bridle or curb" from 1430. One or the other or both took up the main modern meaning of "stopping device for a wheel," first attested 1772.
