Abstract: A wind turbine (10) rotor blade pitch system (42) includes a rotor blade pitch brake (48), a pitch actuator (46), a displacement sensor (52) configured to measure a displacement of the pitch actuator, and a processor (64) communicatively coupled to the displacement sensor and configured to determine a brake wear level corresponding to the displacement of the pitch actuator measured while the pitch brake is engaged.
