A brake system is disclosed, which comprises a parking brake system and an inboard brake pad. The parking brake system includes a first actuator assembly, a second actuator assembly, a motor, and a clutch. The clutch selectively communicates power from the motor to the first actuator assembly so that a first end of the inboard brake pad is moved relative to a brake rotor. The clutch selectively communicates the power from the motor to the second actuator assembly so that a second end of the inboard brake pad is moved relative to the brake rotor. The clutch selectively communicates the power from the motor to both the first actuator assembly and the second actuator assembly so that both the first and the second ends of the inboard brake pad are moved relative to the brake rotor.
