Electronic Brake Force Dis-

tribution (EBD) system

The EBD system maximizes the effective-

ness 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 func-

tion of optimizing the distribution of brak-

ing force. If any of the ABS components

used by the EBD function fail, 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.
