What do you check for during a brake fluid inspection?

During a brake fluid inspection, evaluating the color, clarity, and moisture content is essential for determining the condition of the brake fluid.

The color and clarity of brake fluid can indicate contamination or degradation. Fresh brake fluid is usually clear to light amber, while a dark or murky appearance may suggest the presence of contaminants or the breakdown of the fluid due to moisture absorption and heat exposure over time.

Moisture content is particularly crucial because brake fluid is hygroscopic, meaning it attracts moisture from the air. Elevated moisture levels can lead to a decrease in the fluid's boiling point, increasing the risk of vapor lock during braking. This can cause brake failure or diminished performance.

Therefore, assessing these characteristics during an inspection is vital for ensuring that the brake system functions effectively and safely. The other options, while relevant in some contexts, do not encompass the primary concerns addressed during a brake fluid inspection.
