Which part is not associated with the steering system?

The brake linkage is not part of the steering system because it is specifically designed to engage and disengage the braking mechanism of a vehicle, which operates independently from the steering function. The steering system is responsible for guiding the direction of the vehicle, while the braking system is focused on slowing down or stopping the vehicle.

In contrast, components such as the power steering cylinder, steering knuckle, and tie rod are essential parts of the steering system. The power steering cylinder assists in making the steering process easier by using hydraulic pressure, the steering knuckle connects the steering system to the wheels and allows for turning, and the tie rod transfers the movement of the steering wheel to the wheels, ensuring that when the driver turns the wheel, the wheels respond accordingly. Understanding the specific roles of these components highlights the distinction between steering and braking functionalities in a vehicle.
