EBD (electronic brake force distribution)

Observe the "Important safety notes" section

EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking.

WARNING
If EBD has malfunctioned, the braking system remains available with full brake boosting effect. However, the rear wheels can still lock, e.g. under full braking. This could cause you to lose control of your vehicle and cause an accident. You should therefore adapt your driving style to the different handling characteristics.
