Which part is NOT considered a key component of the steering system?

The brake pads are not considered a key component of the steering system because they are part of the vehicle's braking system rather than the steering mechanism. The steering system is responsible for controlling the direction of the vehicle, and its key components work together to ensure that the driver can steer effectively and safely.

The steering wheel is the main interface for the driver to initiate steering actions. The power steering cylinder assists in reducing the effort needed to turn the wheel, making steering easier, especially in heavier vehicles. The tie rod connects the steering gear to the wheels, allowing the driver’s input to translate into wheel movement. Since brake pads are specifically designed to create friction and stop the vehicle by pressing against the brake rotor, they do not play a role in steering.
