Which of the following is not part of the inspection for brake lines?

Measuring the brake fluid level is not part of the inspection specifically focused on the brake lines themselves. The inspection of brake lines primarily involves examining the physical condition of the lines, such as checking for leaks, which can lead to a reduction in braking performance. Inspecting for cracks in the lines is crucial, as any structural integrity issues can also cause failure during braking. Additionally, looking for rust or pitting is important because corrosion can weaken the brake lines and potentially lead to dangerous conditions.

While brake fluid level is essential for the overall brake system and its functionality, it pertains more to the brake system as a whole rather than directly to the inspection of the brake lines themselves. This distinction is why measuring the brake fluid level does not fall into the specific scope of a brake line inspection.
