What should you check for when maintaining brake fluid?

When maintaining brake fluid, checking the fluid level, discoloration, and moisture content is essential for ensuring that the braking system functions properly and safely.

The fluid level must be adequate to prevent air from entering the braking system, which could lead to a spongy brake pedal and reduced stopping power. Discoloration can indicate contamination or degradation of the fluid, which may affect its performance and brake system efficiency. Moisture content is particularly critical; brake fluid is hygroscopic, meaning it absorbs moisture over time. If the moisture level exceeds a certain percentage, it can lower the boiling point of the fluid, leading to vapor lock during braking and significantly compromising safety.

This combination of checks helps maintain the integrity of the braking system and ensures reliable brake performance, which is crucial for vehicle safety.
