Electronic Brakeforce Distribution (EBD)
Is activated during normal braking (without ABS control) and divides the braking force on the rear wheels.
Normally there is a variation in the front and rear wheels slippage dependent on how hard braking is and how heavily the car is loaded. The Electronic Brakeforce Distribution (EBD) function ensures that the rear wheel speed is 0-2% higher than the front wheel speed. The function is, in principle, load sensing.
The function is controlled by the control module and controls only the valves to the rear wheels. The pump does not operate, the brake fluid is taken up by the receivers.
