The EB8011 is an emergency brake unit manufactured by ELTA Automotive. It is used to provide emergency braking if the vehicle's brakes fail. The unit consists of an emergency brake actuator, an electrical control unit, a pressure switch, and a diagnostic tool. The actuator contains a solenoid and spring which provides the emergency braking force. The electrical control unit receives power from the vehicle's battery and sends the necessary signals to the actuator to engage the emergency brake when needed. The pressure switch is used to detect an emergency braking situation and trigger the actuator. The diagnostic tool helps troubleshoot the system if an issue arises.
