In cars with front-wheel drive, the front is heavier than the rear. This means that during braking, the car's centre of gravity is displaced forwards. This creates the risk of rear wheel locking due to decreased traction.
Electronic Brake Pressure Distribution (EBD) uses solenoid valves in the ABS unit to regulate the braking force of the rear wheels and prevent them from locking. The Electronic Brake Pressure Distribution function is included in the ABS function. The extent of the EBD application ends where the ABS control takes over.
