Light will be lit in red if the brake fluid level of your Ford Focus 2010 is
too low. You should seek professional help immediately after you have noticed
that the Brake System Warning Light is on. Otherwise, the brakes of your Ford
Focus 2010 may stop working while you are driving, which could lead to
extremely dangerous situations.
