Quality brake fluid contains additives that inhibit corrosion and protect these critical components from damage. Regularly flushing and replacing old brake fluid can help extend the lifespan of your braking system.
4. Moisture Absorption: Over time, moisture can find its way into the brake system through microscopic openings in rubber hoses and seals. Moisture-contaminated brake fluid reduces its boiling point significantly and can lead to vapor lock or complete loss of brakes under heavy use. That’s why it’s important to have your brake system inspected regularly and replace any compromised or contaminated brake fluid.
5. Optimal Performance: Using manufacturer-recommended type and grade of brake fluid ensures compatibility with your vehicle’s specific braking system design and materials used in construction (such as rubber seals). This helps maintain optimal performance by ensuring proper lubrication and sealing.

In conclusion, brake fluid is a critical component in the safe operation of your vehicle’s braking system. It facilitates the transfer of hydraulic pressure, dissipates heat, prevents corrosion, absorbs moisture, and helps maintain optimal performance.
