Red Seal Motorcycle Technician Practice Exam

Question: 1 / 400

What can happen if brake fluid is contaminated?

It can improve braking performance

It can lead to brake failure

Contaminated brake fluid can lead to severe consequences for the braking system, including brake failure. Brake fluid is hygroscopic, meaning it can absorb moisture from the atmosphere over time. If the fluid becomes contaminated with water or other substances, it can significantly lower the boiling point of the fluid. This can result in vapor lock, where the fluid vaporizes under heat generated during braking, leading to a decrease in hydraulic pressure and, consequently, brake function. Additionally, contamination can lead to corrosion within the brake components, compromising the integrity of the system and increasing the risk of malfunction.

Given the critical role of brake fluid in ensuring safe braking performance, any contamination can jeopardize the overall safety of the motorcycle and its operator. This underscores the importance of regular inspections and maintenance of the brake fluid to ensure optimal functioning of the braking system.
