Service Brake Assist Chevy Impala(Meaning And Function Explained!)

Did the service brake assist light come up when you are driving and now you are thinking that you are toast? Seeing the service brake assist light on your Chevy Impala might be scary, but it does not have to be that way at all. If you see this light, then it means that the emergency braking system of your car has a problem and may need servicing.

A service brake assist light is a sign that something is wrong with the braking system, and it needs immediate attention before further damage.

In this article, we are going to look at the service brake assist Chevy Impala and why you need to get it looked at when you get the warning brake lights. So, let us get started by first understanding what a brake assist means.

What is Brake Assist?

Brake assist, also known as Emergency Brake Assist or EBA, is an advanced safety system that helps reduce the distance when emergency braking occurs. It helps drivers come to an immediate stop by detecting when the driver applies maximum pressure on the brake pedal and when traveling at a high speed.

Some drivers disengage the brake assist feature since they believe that it makes braking tough and believe it is dangerous. Nevertheless, this is a very safe feature that can be greatly beneficial.

Brake assist is a smart feature that detects when you are panic breaking and generates maximum pressure to the brake pedals in response. For instance, if you are trying to avoid a collision with an object, a person, or another car.

In short, brake assist helps you get that “phew” sigh of relief especially if you were about to hit something or someone on the road. With its help, your car will bring itself to a halt a few feet from the object or the car you were about to collide with. But keep in mind that this does not mean that the feature will automatically stop your car. Some effort from the driver will be needed to help the car brake harder.

Types of Brake Systems

There are three types of brake systems:

Electromagnetic brake system:

Uses an electric motor included in the automobile to help the car come to a stop. You can find this type of brake system in hybrid vehicles. Besides, the electric motor is also used to charge the regenerative brakes and the battery.

Frictional brake system:

As its name suggests, this type uses friction to stop the car from moving. It works by pressing a brake pad against a moving part. As a result, a friction force develops, which helps in halting the automobile.

Hydraulic brake system:

This brake system uses fluid to transmit force into the system, which helps the car stop. It is a self-lubrication braking system; thus, no lubrication is necessary during braking. The hydraulic brake system is mostly used in buses and trucks.

Automatic Brake Assist Systems

Another popular type of brake assist is the automatic brake system. You can find this in most modern cars. With automatic brake assist systems, you do not have to step on the brake pedal of the vehicle. Instead, the car will come to a sudden stop even without your help.

An automatic brake assist system can help prevent crashes especially when the driver is distracted. Its reaction time is much faster than that of the driver. These automatic brake features use camera data and radar technology to detect the surroundings including moving cars, pedestrians, and motionless vehicles. And when it senses a hazardous situation, the system applies sufficient brake pressure to stop the vehicle.

What Does It Mean When It Says Service Brake Assist?

If your car features brake assist, then you have encountered a service break assist warning. But what is it and should you worry? Well, when you see the service brake assist warning, it means that the brake sensor has some issues.

Every modern vehicle has a brake assist light, which is a wired circuit that connects a sensor to the car’s brain or computer. So, when the sensor fails, the braking system light will go on indicating that there is a problem, which needs to be fixed. The good news is that a professional can detect the problem and solve it.

Is Service Brake Assist Same as an Anti-Lock Braking System?

No, the service brake assist is not the same as an ABS, but both are safety features that can help improve your driving experience. ABS is designed to help the driver maintain traction. This is done by allowing the wheels to rotate slowly and reducing the stopping time.

So, if something unexpected happens when you are driving, a combination of the anti-lock braking system and brake assist will provide more control. In short, an ABS is an anti-skid technology that rapidly pumps your brakes during an emergency stop, hence, preventing your car from sliding or skidding.

What Does Service Brake Assist Mean on Chevy Impala?

Chevy Impala is known to have service brake assist failure. Most Chevy Impala owners have reported this issue. Normally, the service brake assist failure is caused by a lot of things. But the most common one is sensor failure. So, when the service brake assist in your Chevy Impala turns on, then you should know that there is a problem.

Some of the common causes of this issue include:

  • Low fluid

  • A leak in lines
  • Sensor malfunction
  • Light malfunction
  • Grounding issue
  • Mileage inspection indication

The first four are the most severe causes of service brake assist failure on Chevy Impala, which should be addressed immediately. Assuming them will impair your car severely causing it to operate unusually and this can lead to an injury or an accident.

Besides, the other issues are not that serious, but they may still be a bother especially when the lights on the dash remain on.

Advantages of a Service Brake Assist

Before we get to fixing the brake feature, we will look at some of its benefits. This will help you appreciate how much it keeps you safe and why it needs immediate attention in case it fails.

  • Providing power for panicked steps
  • Reduces collisions
  • Shortens stopping distance between 20 and 45 percent
  • Assists drivers in driving and stopping swiftly in emergencies

With that said, it is worth mentioning that the extent to which the brake assist can help the driver make an emergency brake also depends on the ability and the strength of the driver.

Can I Drive with Brake Assist Lights On?

If the traction light comes on when you are driving and there are no other warning lights, do not panic. Find a safe place and pull over. Turn off the vehicle, wait for a few minutes then restart it. If it was only a fluke in the TCS system, then the lights should stay off when you turn on the vehicle and continue driving.

However, if the lights come back on even after restarting the car, it is time to get it checked by a mechanic. In the meantime, drive slowly and avoid hard acceleration as this could result in the wheels slipping. Drive gently also if both the traction control light and the ABS warning light go on.

Additionally, if the ABS, TSC, and red main brake warning lights come on at the same time, then do not drive the car until it is fixed. The entire braking system might be damaged, which means that it might not stop when you want it to.

Thus, you might get into an accident and injure yourself if you drive the car in this condition. Instead, stop driving and let your car be towed to the repair shop for an appropriate diagnosis. Only a professional can detect the problem by using a special code reader.
