| Top 3 actions | Pump the pedal, downshift for engine braking, apply the parking brake gradually |
| Keep the engine | Running — you need power steering and brake assist |

A car whose brakes have failed is frightening, but you have more ways to slow it than the brake pedal alone. The sequence below is built for an automatic transmission and is meant to be read in seconds. The single most useful thing you can do before an emergency is know your own car’s shifter and parking-brake controls, because they vary from car to car.
These steps follow standard driver-safety guidance, but some actions depend on your vehicle — the shifter layout, and whether the parking brake is a foot pedal, a hand lever, or an electronic button — so learn your car’s controls and check your owner’s manual. This page explains what to do in the moment; it does not replace a professional repair afterward.

Emergency steps: how to stop an automatic car with no brakes
To stop an automatic car with no brakes, work through these steps in order: stay calm, pump the pedal, downshift for engine braking, apply the parking brake gradually, warn other drivers, and steer to safety. Keep the engine running the whole time so you keep power steering and brake assist. These actions match standard driver-safety guidance for brake failure.
- Stay calm and keep steering. Keep both hands on the wheel, your eyes up, and look for a clear path or a run-off area. Control and a clear target matter more than any single action, and keeping the engine on preserves your power steering.
- Pump the brake pedal firmly. Press the pedal hard and fast several times. In a partial failure or a car without ABS, pumping can build enough hydraulic pressure for some braking. If the pedal sinks straight to the floor, see what a brake pedal that goes to the floor means.
- Downshift for engine braking. Ease off the accelerator and move the shifter to a lower gear, such as L, 2, or manual/sport mode, so the engine slows the car. Step down gradually rather than forcing the lowest gear at speed, which can skid the drive wheels. Do not shift to neutral, because that removes engine braking; here is what neutral actually does.
- Apply the parking brake gradually. Pull or press the parking brake slowly and smoothly, never in one hard yank, because it acts on the rear wheels and can lock them into a skid. For an electronic parking brake, hold the switch; many apply progressively while the car is moving.
- Warn others and steer to safety. Turn on your hazard lights, use the horn, and steer toward flat, open, low-traffic space, or an uphill grade that will help slow you down.
- Last resort: scrub speed safely. If you still cannot stop, bleed speed with controlled contact: rub the tires against a curb, or the side of the car along a guardrail or brush at a shallow angle. Trading paint for a stop beats a high-speed impact.
- Once stopped, do not drive. Get fully off the road, shift to park, leave the hazards on, and call for a tow. Brakes do not fix themselves, so driving on a failed system risks another failure.
What NOT to do if your brakes fail
What you avoid matters as much as what you do, because the wrong move can take away the control you have left. Do not switch off the engine, shift to park or neutral at speed, or yank the parking brake. Each one can turn a bad situation into a worse one.
- Don’t turn off the engine while moving: you lose power steering and brake assist, and the steering can lock.
- Don’t shift to park at speed: it can wreck the transmission and lock a wheel.
- Don’t shift to neutral as your first move: it removes engine braking, one of your best tools for slowing an automatic.
- Don’t yank the parking brake: a hard pull can lock the rear wheels and send you into a skid.
- Don’t pump an ABS pedal before trying firm pressure: with ABS, press and hold hard first, and pump only if that does nothing.
Why do brakes fail, and how do you prevent it?
Brakes usually fail from a loss of hydraulic pressure or from overheating, and most failures give warning signs first. The common causes are a fluid leak or low fluid, severely worn pads, a failing master cylinder, and brake fade from overheating on a long descent. A soft pedal or a brake warning light is the warning, so treat it as a reason to act now rather than later.
| Cause of brake failure | Warning sign you notice first | How to prevent it |
|---|---|---|
| Fluid leak or low brake fluid | A soft or spongy pedal, or a pedal that sinks | Check the fluid level and color; fix any leak early |
| Severely worn brake pads | Squealing that turns to grinding; longer stops | Replace the pads at the first wear-indicator squeal |
| Failing master cylinder | The pedal slowly sinks under steady pressure | Have it inspected at the first sign of a soft pedal |
| Brake fade from overheating | Weak brakes and a burning smell on a long descent | Downshift on long hills instead of riding the brakes |
- Keep the fluid right: a leak or old fluid is a top cause of failure; see how to add brake fluid and check the level and color.
- Don’t ignore worn pads: read the cost of ignoring brake problems, and here is how to test your brakes at home.
- Understand the system: knowing how a car brake system works makes the warning signs easier to read.
- Check for recalls and use a qualified shop: look up your VIN on NHTSA’s recall tool, since brake recalls are repaired free, and have repairs done by an ASE-certified technician.
Frequently asked questions
Should I shift to neutral if my brakes fail?
Shifting to neutral is not the right first move if your brakes fail, because neutral removes engine braking, which is one of the best tools for slowing an automatic. Downshift to a low gear instead. Only consider neutral if the car is accelerating on its own and you need to cut power to the wheels.
Will the parking brake stop an automatic car?
The parking brake can help slow and eventually stop an automatic car, but it acts on the rear wheels only and works best applied gradually. Yanking it at speed can lock the rear wheels and cause a skid, so apply it smoothly and use it as one part of the sequence, not on its own.
Should I turn off the engine if my brakes fail?
Turning off the engine while moving is not safe if your brakes fail, because it kills power steering and brake assist and can let the steering lock, making the car much harder to control. Keep the engine running until you have come to a complete stop, and only then switch it off.
What causes total brake failure?
Total brake failure is most often caused by a loss of hydraulic pressure, from a fluid leak, severely worn pads, or a failed master cylinder, or by brake fade from overheating on a long descent. Most cases show warning signs first, such as a soft pedal or a brake warning light.
What to do now
Memorize the sequence — pump, downshift, gradual parking brake, steer to safety — and learn your car’s shifter and parking-brake type before you ever need them. Never ignore a soft pedal or a brake warning light, because most failures warn you first, and catching one early is how you avoid the emergency altogether.
If your brakes fail, keep the engine running, slow the car with engine braking and the parking brake, steer to open space, and once you stop, do not drive — tow it and have the system repaired.
