BRAILS. Ropes passing through leading blocks on the hoops of the mizen-mast and gaff, and fastened to the outermost leech of the sail, in different places, to truss it close up as occasion requires; all trysails and several of the staysails also have brails.
BRAIL UP! The order to pull upon the brails, and thereby spill and haul in the sail. The mizen, or spanker, or driver, or any of the gaff-sails, as they may be termed, when brailed up, are deemed furled; unless it blows hard, when they are farther secured by gaskets.
BRAKE. The handle or lever by which a common ship-pump is usually worked. It operates by means of two iron bolts, one thrust through the inner hole of it, which bolted through forms the lever axis in the iron crutch of the pump, and serves as the fulcrum for the brake, supporting it between the cheeks. The other bolt connects the extremity of the brake to the pump-spear, which draws up the spear box or piston, charged with the water in the tube; derived from brachium, an arm or lever. Also, used to check the speed of machinery by frictional force pressing on the circumference of the largest wheel acted on by leverage of the brake.
