What connection does a drag link have in a steering system?

The drag link plays a crucial role in the steering system by connecting the steering gear to the pitman arm. This connection facilitates the transfer of motion from the steering wheel, through the gear mechanism, to the pitman arm, which then translates that motion into left or right turning of the vehicle's wheels.

When the driver turns the steering wheel, the steering gear converts that rotational movement into linear motion, which is then conveyed via the drag link to the pitman arm. This action ensures that the wheels respond appropriately to the driver's inputs, maintaining control and maneuverability of the vehicle.

The other options pertain to different components and functions within the vehicle's systems. For example, the connection between the steering wheel and the steering column is typically made through the steering shaft, and the tie rods connect the pitman arm to the steering knuckles for wheel direction control. The brake system's operation involving the brake pedal and brake calipers is entirely separate and not relevant to the steering system.
