Clutch for a parking brake system

An assembly comprising:

• a. a brake caliper including:
• i. a brake pad;
• and
• b. a parking brake system including:
• i. a first actuator assembly in communication with a first end of the brake pad;
• ii. a second actuator assembly in communication with a second end of the brake pad;
• iii. a motor gear unit in communication with the first actuator assembly, the second actuator assembly, or both, and
• iv. an electromechanical clutch comprising a coupler and a solenoid,
• wherein electrical power is sent to the solenoid so that the coupler moves in a first direction and engages a second gear so that power from the motor gear unit is communicated only to the first actuator assembly so that the first end of the brake pad is moved relative to a brake rotor, and
• wherein electrical power is sent to the solenoid so that the coupler moves in a second direction and engages a third gear so that the power from the motor gear unit is communicated only to the second actuator assembly so that the second end of the brake pad is moved relative to the brake rotor.

A method comprising:

• moving a coupler into a first position so that power from a motor is communicated to a first actuator assembly so that a first end of a brake pad is moved relative to a brake rotor;
• moving the coupler into a second position so that the power from the motor is communicated to a second actuator assembly so that a second end of the brake pad is moved relative to the brake rotor;
• and
• moving coupler into a third position so that the power from the motor si communicated to both the first actuator assembly and the second actuator assembly so that both the first end of the brake pad and the second end of the brake pad are moved relative to the brake rotor.
