An Etymological Dictionary of the German Language/Bremse
Bremse, f., ‘drag-shoe,’ from MidHG. bręmse, f., ‘barnacle, muzzle.’ It cannot be identified with Bremse, ‘gadfly’ (see Breme), because the latter indicates a Goth. brimisi, while Bremse, ‘drag-shoe,’ points to a Goth. bramisjô. For Bremse, ‘drag,’ dialectal forms such as bram (with a and the loss of the suffix s) have been authenticated, but of a root bram with some such meaning as ‘to press, squeeze,’ there is no trace, The suffix s recalls Goth. jukuzi, ‘yoke,’ from the equiv. juk; comp. also aqizi, ‘axe.’
