What should you do if your brakes fail? Hook your shoe under the pedal and see if you can free it. Pull the steering wheel back. Turn on your cruise control. Try pumping the brake pedal to increase pressure.

Try pumping the brake pedal to increase pressure.

Explanation:

When the brake of a vehicle fails when driving, it's important to pump the brake pedal to increase pressure.

Sometimes, there may be a soft brake due to the fact that the brake master cylinder of the vehicle cannot full pressure which is necessary for the braking power.

One should quickly pump the brake pedal with his or her foot so as to generate enough pressure which will be necessary in stopping safely.

This isn't true because the exact answer of a system is where the lines cross each other, not where they cross a grid.
