Using a clean funnel, carefully add the recommended brake fluid to the reservoir until it reaches the maximum mark.
Avoid overfilling.

4. Inspect for Leaks

Inspect all brake lines, connections, and the master cylinder for leaks.
If leaks are found, determine the source and replace the affected components.

5. Reassemble and Test

Replace the brake fluid reservoir cap securely.
Start the engine and pump the brake pedal several times to ensure pressure builds.
