Abstract
A yaw brake for a wind turbine includes a brake housing disposed on one or both sides of a brake surface disposed about a yaw axis. The housing defines a bore and a piston is disposed within the bore. The piston is configured for movement within the bore along an axis between first and second positions in which the piston applies different braking forces to the brake surface. At least one portion of the piston and at least one portion of the bore of the brake housing have complementary non-circular shapes. The at least one portion of the piston is configured to be positioned within and least one portion of the bore when the piston is in the first and second positions. A bushing is disposed radially between the at least one portion of the piston and the at least one portion of the bore of the brake housing.
