Description And Operation: Operation: Notes

The EBD system (Electronic Brake force Distribution) as a sub-system of the ABS system is to control the maximum braking effectiveness by the rear wheels.

It further utilizes the efficiency of highly developed ABS equipment by controlling the slip of the rear wheels in the partial braking range.

The brake force moves closer to the optimum and is controlled electronically, thus being dispensed with the need for the proportioning valve.

The proportioning valve, because of a mechanical device, has limitations in achieving an ideal brake force distribution to the rear wheels as well as carrying out the flexible brake force distribution proportioning to the vehicle load or weight increasing. And in the event of malfunctioning, drivers cannot notice the failure.

EBD controlled by the ABS Control Module, calculates the slip ratio of each wheel at all times and controls the brake pressure of the rear wheels not to exceed that of the front wheels.

If the EBD fails, the EBD warning lamp (Parking brake lamp) lights up.
