What can indicate the need for a deeper assessment of a vehicle's brake system?

The condition of the brake fluid is a critical indicator of the health of a vehicle's brake system. When brake fluid is excessively dirty or below the minimum level, it suggests potential issues such as contamination, moisture absorption, or insufficient fluid for proper brake operation. Contaminated brake fluid can lead to corrosion of brake components and reduced braking efficiency, which poses significant safety risks. Therefore, observing dirty or low brake fluid should prompt a thorough examination of the entire brake system to identify any underlying problems that need to be addressed.

In contrast, functioning lights, new tires, and correct vehicle alignment, while important for overall vehicle safety, do not specifically relate to the performance or integrity of the brake system. These factors might contribute to the overall driving experience but do not warrant the same level of concern as brake fluid condition.
