Which component is NOT part of the steering system?

Steering wheel
Tie rod
Brake pads
Power steering cylinder

The correct answer is: Brake pads

The brake pads are not part of the steering system; instead, they are components of the braking system. The purpose of brake pads is to create friction with the brake rotors to slow down or stop a vehicle. In contrast, components like the steering wheel, tie rod, and power steering cylinder all play crucial roles in vehicle steering. The steering wheel allows the driver to control the direction of the vehicle, the tie rod connects the steering gear to the wheels and helps in transmitting the driver's steering inputs, and the power steering cylinder assists in making steering easier by using hydraulic pressure. Understanding these distinctions is vital for safety and vehicle operation.
