Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Inspect and Repair Brake Fluid Leaks

Locate the Leak: Identify any leaks in the brake lines, calipers, or master cylinder.
Replace Damaged Components: If leaks are found, replace the affected brake line, caliper, or master cylinder.
- Tools Required: Wrench set, brake line flaring tool (if applicable).
