You drive an older car that has no split brake system. The brake pedal suddenly goes to the floor, and the car does not slow down. You have shifted to a low gear. What should you do next?
A close view shows a broad brake pedal and a narrower accelerator. The card states that this older car has no split brake system, the brake pedal sank without slowing the car, and low gear is already selected.
Correct answer: Pump the brake pedal fast several times to build up pressure.
Why
Newer cars have a split brake system, so a failure often leaves braking on two of the four wheels: the pedal goes lower, and you must push harder. In an older car, a full failure needs a set of steps: low gear, pump the pedal, then the parking brake with the release held. Keep your eyes on your path, and look for an open place or an uphill road where you can slow down safely.
