The purpose of a brake line is to transport brake fluid from the master cylinder to the brake components. In a hydraulic braking system, brake lines play a crucial role in transmitting the force applied to the brake pedal through the brake fluid, allowing for efficient braking action. When the driver presses the brake pedal, it creates pressure in the master cylinder. This pressure is then transferred through the brake lines to the brake calipers, which engage the brake pads and ultimately slow down or stop the vehicle.

This function is essential for the system's effectiveness, as any failure in the brake line can lead to loss of fluid and pressure, resulting in a potential brake failure. The other choices do not pertain to the fundamental role of brake lines within the braking system, as they do not accurately describe the transportation and hydraulic function that is central to braking performance.
