Abstract

The invention relates to a hydraulic braking device for a yaw drive in a nacelle of a wind turbine comprising a brake disk ring rotationally fixed to the nacelle a plurality of disk brakes distributed over the circumference of the brake disk ring being associated with said brake disk ring. According to the invention at least one disk brake is provided with a friction lining arrangement that differs from the other disk brakes the friction coefficient of said friction lining arrangement being reduced compared to the other disk brakes.
