GAC GM8 2.0T Rear ABS Sensor R8030005-AMV0100 Left/Right Universal

When your GAC GM8 2.0T shows ABS warning on the dashboard during driving, or the brake pedal feels spongy on hard braking, or braking distance increases, or wheels lock/slip, this typically indicates the rear wheel ABS sensor has aged or failed, causing wheel speed data loss. When functioning normally, it monitors wheel speed in real time and feeds data to the ABS control unit to precisely modulate braking force during emergency braking, preventing wheel lock and ensuring stability. OEM number R8030005-AMV0100, left-right universal, fits GAC GM8 2.0T. Installation: disconnect battery negative first, clean iron debris and dirt from the mounting holes, and torque to factory spec to avoid wiring damage.
