What is a Secondary Collision Brake System?
The secondary collision brake system is an advanced safety feature designed to automatically apply the brakes after a primary collision.
Its purpose is to prevent or minimize the severity of secondary collisions with other vehicles or objects.
When a primary collision occurs, the system uses information from the electronic stability control system and deploys the brakes to decelerate the vehicle, reducing the risk of further accidents.
Signs of a Secondary Collision Brake System Malfunction
Detecting a malfunctioning secondary collision brake system is crucial for the safety of both the driver and passengers. Here are some common signs to look out for:
Useless Brake Effect
One of the most apparent signs of a malfunctioning secondary collision brake system is the lack of any reduction in vehicle speed after a primary collision.
If the vehicle continues to rush forward without any braking effect, it indicates a problem with the secondary collision brake system.
Another sign of a malfunction is when the secondary collision brake system is unexpectedly activated even in the absence of a collision.
This can pose a significant risk, especially when driving at high speeds, as sudden braking can lead to accidents with other vehicles.
Excessive Brake Intensity
A malfunctioning secondary collision brake system may apply the brakes with excessive force after a primary collision.
This forceful brake intensity can cause the driver’s body to jerk forward, potentially resulting in chest and shoulder injuries.
Vehicle Pulling to One Side
If the vehicle pulls to one side when hard braking is applied, it could be an indication of a malfunctioning secondary collision brake system.
This deviation from the vehicle’s original trajectory can affect the overall control and stability of the vehicle.
