EBD Explained: Electronic Brakeforce Distribution

EBD (Electronic Brake Force Distribution) is a technology that enables the braking force of a vehicle to be increased or applied automatically, depending on road conditions, speed of the vehicle, weight of vehicle, etc.

In a regular braking system, when the brake pedal is applied, the brake fluid travels from the master cylinder to the brake cylinders. When the fluid goes inside the brake cylinder, the pressure of the fluid being applied forces the two pistons to push out resulting in the brake shoes or pads being pushed out. This push or pressure is in direct proportion to the push by the pistons, which causes the shoes or pads to rub against the drum or caliper. This reaction creates friction and decreases the turning of the wheels.

What EBD does is it electronically monitors, through sensors, the conditions of the road, the feel of pressure on the brake pedal, and vehicle weight, to determine when to apply pressure to the wheel cylinders. The sensors are designed to monitor the movements of the wheels and determine based on weight, which wheels may need the maximum force applied, as per the condition met. Supposedly, this is to provide better and more precise braking under every condition imaginable.

Since the front end has the most weight on a vehicle, the EBD system recognizes this and electronically controls the back brakes so when the driver applies the brakes, the back brakes do not lock up causing a skid.

EBD is a good system for drivers because it can increase the vehicle’s ability to stop under any conditions. But this is only effective if the brains of the computer works, along with the sensors that make up the system. If one of those sensors should fail, and you run into a bad situation, you could end up in a precarious predicament.
