Can you use hydraulic fluid in your brake system?

No, hydraulic fluid should not be used in your brake system unless it is specifically designed for that purpose. Brake systems typically require brake fluid that meets specific standards, such as DOT (Department of Transportation) ratings, which are formulated to handle the high temperatures and pressures involved in braking. Using the wrong fluid can lead to brake failure, damage to components, and compromised safety. Always refer to your vehicle's manual for the correct fluid specifications.
