System Description: Operation
- When the electric parking brake switch is pulled, a parking brake operation switch signal is transmitted from the electric parking brake control unit to the parking brake actuator.
- When the parking brake actuator receives a electric parking brake switch signal, it activates the motor in the parking brake actuator.
- When the motor is operated, rotating torque is generated, and transmitted to the piston in the parking brake actuator of the rear brake caliper via gears in parking brake actuator and belts in the parking brake actuator.
- The piston is pushed out by the rotating torque, and the parking brake operates by pressing the brake pad against the disc rotor.
