The EBD system, guided by data on the vehicle's deceleration rate and wheel slip, controls the electromagnetic valves, increasing or decreasing the brake fluid pressure in the rear brakes. Thus, EBD improves both the vehicle's braking force and its controllability and stability. Also, thanks to EBO, the driver does not need to press the brake pedal harder in a more loaded vehicle or when driving on a slippery surface.
Thanks to the optimal distribution of braking forces between the axles, the load on the front brakes is reduced, which increases the service life of the brake pads and discs.
