Which component in a vehicle's braking system may affect steering and suspension if it is not working correctly?

In the context of a vehicle's braking system, the ball joints are critical components that can significantly influence both steering and suspension performance if they are not functioning properly. Ball joints connect the control arms of the suspension system to the steering knuckles, enabling smooth movement and articulation of the vehicle’s wheels during steering and while driving over different road surfaces.

When ball joints wear out or fail, they can lead to excessive play in the suspension system, which not only affects the handling and stability of the vehicle but can also impact the braking performance by affecting the angle and alignment of the wheels. This misalignment can lead to uneven tire wear, compromised steering accuracy, and a reduction in braking efficiency, particularly when the vehicle is coming to a stop or making a turn.

Since the braking system is closely linked to both the steering and the suspension, any failure in the ball joints could create a situation where steering control and suspension response are compromised during braking maneuvers. That's why addressing issues with ball joints is crucial for ensuring that the vehicle operates safely and effectively across all systems.
