What should you do in case of a brake failure, even after pumping the pedal does not build up the pressure?

• Pump the pedal vigorously.
• Use the emergency or parking brake gently.
  Explanation:

  "If pumping the pedal does not build up the pressure, use your emergency or parking brake, but apply gently so that you do not lock the brakes and throw your car into a skid."
• Apply the brakes more forcefully.
• Shift to a lower gear.
