FRONT WHEEL BRAKE PRESSURE
The electronic brake distribution (EBD) feature helps control vehicle braking by adjusting the rear brake force in
accordance with the rear wheel load before the ABS operates. Based on the wheel speed sensor signals, the control
unit uses the modulator to control the rear brakes individually. When the rear wheel speed is less than the front wheel
speed, the ABS modulator-control unit retains the current rear brake fluid pressure by closing the inlet valve in the
modulator. As the rear wheel speed increases, and approaches the front wheel speed, the ABS modulator-control unit
increases the rear brake fluid pressure by momentarily opening the inlet valve. This whole process is repeated very
rapidly. While this is happening, kickback may be felt at the brake pedal.
