Electronic Brakeforce Distribution
system – EBD
The Electronic Brakeforce Distribution
system (EBD) is an integrated part of the
ABS system. The EBD system controls the
brake force to the rear wheels so that the
best possible braking force is always
available. Pulses will be heard and felt
through the brake pedal when the system
regulates brake force.
WARNING!
If the BRAKE and ABS warning symbols
are lit at the same time, a fault may have
occurred in the brake system. If the level in
the brake fluid reservoir is normal, drive
carefully to the nearest authorised Volvo
workshop to have the brake system
checked.
If the brake fluid is under the MIN level in
the brake fluid reservoir, do not drive
further before topping up the brake fluid.
The reason for the loss of brake fluid must
be investigated.
Emergency Brake Assistance – EBA
(Emergency Brake Assistance) In case of
sudden braking, full-strength braking is
provided instantaneously. The EBA function
senses when heavy braking is underway by
registering how quickly the brake pedal is
depressed. Continue braking without easing
off on the brake pedal. The function is
suspended when the pressure on the brake
pedal eases. This function is always active
and cannot be disengaged.
