If while driving, you apply the
foot brake and the pedal goes to the floor, it’s an indication of a failed
brake. In such a case, the first thing to do is to shift to a lower gear. The
second step is to pump the brake pedal fast and hard two to three times in
order to build up brake fluid pressure. The third step if the brake still doesn’t
respond after step 2 is to use the parking brake.
