Prefill Braking

Another simply clever element of the Electronic Stability Control system is Prefill. Your Octavia will recognise when your foot has abruptly lifted off the accelerator and anticipates that this may be followed by a sharp depression of the brake pedal. To prepare for this braking, your Octavia automatically increases pressure in the brake system by "prefilling" the brake hydraulics with fluid. It also brings the brake pads closer to the discs. This speeds up the braking effect for optimal stopping.​
