What to do if…
your brakes fail while you are driving

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Take your foot off the accelerator, keep steering smoothly, and press the brake pedal firmly. If the vehicle does not slow, pump the pedal, shift to a lower gear, apply the parking brake gradually, and steer toward a clear place to stop.

Do not do these things

  • Do not make sudden steering movements.
  • Do not shift into Park or Reverse while the vehicle is moving.
  • Do not apply the parking brake suddenly.
  • Do not look down at the controls for longer than necessary.
  • Do not handle a phone while you need both hands and your full attention to control the vehicle.
  • Do not turn an ignition key to Lock or remove it while moving.
  • Do not drive the vehicle again after you stop.

What to do now

  1. Take your foot fully off the accelerator. Hold the steering wheel securely, look where you want the vehicle to go, and keep steering smoothly.
  2. Press the brake pedal firmly. If it feels hard, keep steady pressure and press harder than usual. If it drops close to the floor or gives little response, pump it quickly several times to try to rebuild pressure.
  3. Shift into a lower gear or low range so the engine helps reduce speed. Do not select Park or Reverse.
  4. Apply the parking brake gradually. If the wheels lock or the vehicle begins to skid, ease off until steering control returns, then apply it more gently.
  5. Turn on the hazard lights if the control is within easy reach. Use the horn when needed to warn nearby drivers or pedestrians.
  6. Steer toward a clear shoulder, open area, or uphill road where the vehicle can lose speed. Keep looking and steering toward the clearest, lowest-risk path available.
  7. Ask a passenger to call 911 if a crash or immediate danger appears likely. If you are alone, keep controlling the vehicle and call after stopping rather than handling the phone.
  8. Once stopped, select Park or a low gear, set the parking brake, turn on the hazard lights, and switch off the engine. Call 911 if anyone is injured or the stopped vehicle creates an immediate traffic danger.
  9. Arrange roadside assistance or a tow. Do not attempt to drive the vehicle to a repair shop.

What can wait

You do not need to diagnose the failure, inspect the brakes, choose a repair shop, check for recalls, contact your insurer, or decide who may be responsible while the vehicle is moving. Those tasks can wait until everyone is safe and the vehicle is secured.

Important reassurance

Brake failure may still leave more than one way to reduce speed. Concentrating on steady steering and using the available slowing methods carefully can help you retain control and reach a safer stopping place.

Scope note

This guide covers only the first actions during and immediately after suspected brake failure. Inspection, repairs, insurance questions, crash reporting, and later decisions may require a qualified mechanic, roadside provider, insurer, law-enforcement agency, or other specialist.

Important note

This is general driving-safety information, not mechanical, legal, emergency-response, or other professional advice. Vehicle braking systems and controls differ, so follow emergency-service instructions and your vehicle owner’s manual where possible.
