Electronic Brakeforce Distribution (EBD)

It is a software function of the ABS system. It adapts to load, for example when the boot is full. It replaced mechanical brake pressure regulators on most cars. EBD works continuously in normal braking, not only in emergencies. It allows rear brakes to do more work when the car is loaded, shortening stopping distances.

The ABS unit monitors wheel speeds and limits pressure to the rear brakes to prevent them locking before the fronts.

An EBD fault usually lights the ABS and brake warning lights together and needs prompt attention. Use parts specified for the vehicle, as pad friction affects the balance.
