Secondary Collision Brake System Malfunction – Fix To Save Yourself

Secondary collision brake system malfunction can cause a higher risk of accidents. Without the protection of this component, drivers easily face serious injuries that can damage their lives.

That’s why drivers can not hesitate to have a specialized auto service center fix it, especially when your job is to pick up passengers, tourists, etc.

Is there any reliable way to detect a broken second collision brake system? Do not worry, as we are going to provide some key information in the upcoming sections.

Signs To Detect Secondary Collision Brake System Malfunction

Secondary Collision Brake System Malfunction

A second brake system applies brakes to prevent or alleviate further impact when the vehicle encounters a collision.

As the airbag is activated in the primary crash,  the electronic stability control system detects the information to brake the car.

The vehicle will automatically decelerate to avoid a secondary collision, such as with another vehicle or roadside objects, or at least a less severe impact.

During braking, the hazard and brake lights will be glowing,  remaining on after the brake has stopped.

In a severe primary collision, the driver may not be able to control the vehicle. It’s time for a second brake system to safely slow down the vehicle speed.

The brake’s benefits are so important that you have to detect any problems as soon as possible. You can easily identify a broken brake through the 4 signs below.

Useless Brake Effect

After the primary crash, the vehicle continues to rush forward without any reduction of current speed, causing continuous collisions with other vehicles on the road or other objects.

It is the most typical and accurate warning of a malfunctioning second brake system. However, it is too late if you wait for this to actually happen. You will be at a considerable risk of serious injuries.

Sudden Operation

The second brake system is unexpectedly activated even though there is no collision. It is also extremely dangerous when you are driving on the highway.

Your car slows down or even stops suddenly on the way. Other vehicles moving at high speed may not be able to brake in time and crash into your car.

Too Forceful Brake Intensity

After the primary crash, the brakes operate so intensely that it shocks the driver. Thr driver’s bodies can hit the steering wheel, causing chest and shoulder muscle injuries.

This situation may also suggest that you should have an automotive technician detect the second brake system errors.

Car Pulls To One Side When Braking Hard

When braking takes effect, the vehicle may be deflected to one side, not maintaining the original trajectory (straight lines).

It also needs paying attention to; there is a high chance that both front brake calipers don’t release.

What Causes The Secondary Collision Brake System Malfunction?

Secondary brake system failure occurs for various reasons, from electronic to installation errors.

Blocked hydraulic lines or valves and other broken engine components can also affect the brake’s performance.

Here are the most common reasons for the secondary collision brake system malfunction toyota:

Improper installation

A brake system requires a complicated installation that links several components together. Some car owners replace the brake system parts at home, such as the brake pad.

Improper installation of any detail can also lead to brake operation errors. Therefore, it is wiser to have your brake system serviced by a qualified technician.

Defective Components

As we mentioned, the brake system works on a combination of sophisticated details. A defective component is sufficient to mitigate the braking efficiency.

Your brake lines may be stuffed by air. The air compression whenever air flows through the brake lines can interfere with contact between the brake pedal and the brake.

As such, you will witness the reduced effectiveness of the whole process.

The pressure drop in the brake system due to leakage in brake lines is also a notable case.

Brake fluid can drain through the holes located on the brake line.

This way, no pressure is generated regardless of pressing the brake pedal. The whole brake system and the calipers are on the verge of damage.

The master cylinder can face a problem too, enabling the fluid to flow into the seals. Not only does this error decrease the brake efficiency, but worse, it also neutralizes your brake.

Blocked Hydraulic Lines Or Valves

Brake fluid can draw moisture through the brake hose into the hydraulic system.

As a result, moisture can damage, jam anti-lock brake system valves, and corrode the sensitive inner surfaces of brake calipers and wheel cylinders.

Poor quality brake fluid also contains air, making the brake pedal spongy or insensitive.

If the brake fluid is not drained from the system, it can cause a second brake system to malfunction over usage time. That’s why you need to flush the brake fluid properly.

Electronic Fault In Control Unit

Due to electronic errors, the brakes can fail to receive information about the initial crash to slow down the vehicle speed.

The manifestation of an electronic error can be the brake light signal on the check engine light.

Secondary Collision Brake System Malfunction – How To Fix?

You can try doing a few simple checks at home before taking it to a repair center. Your inspection can somehow support the qualified technician to catch the problem more quickly.

Check The Hydraulics System

Hydraulics system and brake fluid are among the typical warning messages of a broken second brake.

So, as the first step, check the condition of the hydraulic valve and the brake fluid. Leaky hydraulic fluid or clogged hydraulic lines are what you should pay attention to.

Check Relating Brake Components

No abnormality detected in the hydraulic lines? Let’s move on by checking all related components, especially the master cylinder and brake calipers.

You may mark the installation fault or wear, then have them serviced or replaced if needed.

Diagnostic Scanner Test

A diagnostic scanner is a useful modern device for car owners.

Connected to the vehicle via OBD, the device can diagnose the vehicle status and read the fault memory as well as the recorded data on the vehicle system. Even better, it will announce drivers the time for the brake’s replacement.

This device is used in professional auto repair shops, so you can count on its accuracy.

The diagnostic scanner is no longer a rare product on the market. Car owners can consider buying if their budget allows.

Check Cruise Control 

It’s likely that drivers will overlook the cruise control, which could also be a cause of brake failure.

Damaged cruise control will not be able to detect the crash signal, therefore not decelerating the car in such a case.

Car drivers can unintentionally hurt the battery while trying to restart cruise control. We suggest that it should be fixed by a qualified technician.

Pre-collision Brake System Malfunction How To Fix?

The pre-collision brake system continuously monitors the driving process as well as the conditions on the way, such as obstacles, vehicles ahead, oncoming vehicles, etc., to detect the risk of an accident a few seconds before the collision.

It implements warning and intervention measures to prevent or minimize possible damage.

Generally, this brake system fails due to problems with pre-collision sensors.

Among them, dirty sensors are the ultimate reason. Over usage, extreme weather agents such as ice, snow, litter, or even intense sunlight can reduce the sensor’s sensing capabilities.

The wisest solution is to clean the sensor.

Additionally, a failed airbag sensor is another thing explaining the improper operation of pre-collision systems.

You can fix the error yourself by resetting the pre-collision systems. However, this solution is only applied for minor, easy-to-fix errors.

If the critical fault involves complicated electronics engineering, you should let an auto technician tackle the issues.

Please try disconnecting the battery for a while, then reconnecting it. Do not forget to check the fuse box before fixing to avoid electrical or fire hazards.

Your practice can reset the vehicle’s electronic system, including the pre-collision brake.

If you don’t get a positive result, take it to a service center as the last resort to treat the pre collision system malfunction Toyota camry 2020.

How To Reduce The Risk Of  Pre Collision System Malfunction Toyota?

Toyota is extremely proud of the excellence of its pre-collision systems, aided by sub-features called Brake Assists – extra braking power and seatbelt pretensioners – automatic seatbelts in a crash.

Besides the main function of accident minimization, this system can also reduce the seriousness of a collision.

Claimed to reach the top quality, Toyota PCS still exhibits certain weaknesses, leading to malfunction possibility.

To minimize the risk, always bear in mind to regularly maintain your vehicle at reputable service centers or Toyota service centers.

We sincerely advise that you take the initiative to check and prevent errors from the vehicle’s brake system. It will be too late if you detect brake failure in the collision.

No matter how modern it is, the collision brake system’s electronics are sometimes flawed. It does not absolutely guarantee avoidance of accidents and serious injuries for the driver.

As the final word, we hope you should not rely on the brakes too much. The best way to protect yourself is to drive safely and obey traffic regulations.
