ELECTRIC PARKING BRAKE SYSTEM


  1. CONSTRUCTION


    1. The parking brake with bracket actuator assembly is constructed with a motor, each gear, emergency release gear, clutch, shaft, equalizer and tension sensor, and is connected to each cable.

    2. When a lock signal is received from the parking brake ECU assembly, the motor will wind up the parking brake cable by rotating the shaft, thus locking the parking brake.

    3. When the motor stops rotating, operation of the clutch maintains the pulling force of the parking brake cable.

    4. When a release signal is received from the parking brake ECU assembly, the motor turns in the opposite direction to reduce the pulling force of the parking brake cable, thus releasing the parking brake.
