No friction at all? The car would never stop. No friction on the brakes, same. No friction on the road from tires? same. Even if it were 'on ice' like above it would still stop because there is friction on ice, just less. If there is NO friction, the car wouldn't stop.
If there was no friction, the car would probably not have stopped immediately the driver hit the brakes. Without friction, the car would just move forward as if it were on ice. Visit http://www.theweatherprediction.com/habyhints/10/ for details.
