Subaru Legacy: Electronic Brake Force Distribution (EBD) system - Starting and operating - Subaru Legacy Owners ManualSubaru Legacy: Electronic Brake Force Distribution (EBD) system

The EBD system maximizes the effectiveness of the brakes by allowing the rear brakes to supply a greater proportion of the braking force. It functions by adjusting the distribution of braking force to the rear wheels in accordance with the vehicle’s loading condition and speed.

The EBD system is an integral part of the ABS system and uses some of the ABS system’s components to perform its function of optimizing the distribution of braking force. If any of the ABS components used by the EBD function fails, the EBD system also stops working.

When the EBD system is operating, you may hear a chattering noise or feel a slight vibration in the brake pedal. This is normal and does not indicate a malfunction.
