They dont stop with brakes, just turn the blades. When the wind gets even stronger, turn the whole head. The Rotor is way to heavy to be stoped by brakes alone.<br>Not so Fun Fact: There are cases were they burned down after brakes overheating,(reply>), @SCREAMIN' LORD BYRON all wind turbine have aerobraking with the blades and also disk brake. Some use the disk brake, some don't,depends on the manufacturer, model, type of braking( manual stop, emergency stop...),(reply>), MazeFrame so they don't stop with brakes but there was a case of brakes overheating and burning one down. Well explained,(reply>), @pmailkeey the turbine dose feather, then engages the brakes when under a certain speed,(reply>), @patrick batemon Brakes would be the last thing I'd consider for dealing with strong winds. Feathering the blades would be the obvious thing to do and could be mechanically automated.,(reply>), @Winston Smith They'd overspeed and blades would break off !
