How Brake Failure Works

How to Handle Brake Failure

Complete brake failure in modern vehicles is rare, but it can happen. This can be the result of a defective brake system from the manufacturer, so pay attention to recall notices. Total brake failure could also occur if all the brake fluid has leaked out. Fortunately, most of us would notice either a leak or a sound before that happened.

One common temporary brake failure occurs when the vehicle hydroplanes. This happens when the brakes are wet, usually after driving through a deep puddle. If you experience this, remove your foot from the accelerator. Hold the steering wheel straight. Do not swerve or jerk the vehicle. This way, the vehicle will slow down and you can regain control of the car [source: Midas].


Perhaps the most important action a driver can take when the brakes fail is to remain calm. Panicking doesn't help. The next step -- the first action step -- is to lift the foot from the accelerator. Notice the flow of traffic and any obstacles or pedestrians, and look for a place to pull over safely. Then try downshifting to a lower gear, whether your vehicle is an automatic or a standard. This is called engine-braking. As the vehicle slows down, keep shifting to lower gears.

Once the vehicle is moving at 30 mph or less, you can try engaging the parking brake. Because it is a separate system from the regular brakes, it should still work.

As a final resort, put the car in reverse. But remember, this could destroy the car, so never use it as a first response.

Try to maneuver the car off the road if possible as you come to a complete stop. Turn your hazards on and call or wait for help.
