Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles to protect against brake fluid.

2. Inspect and Clean the Brake System

Tools Required: Brake cleaner, lint-free cloth.
Remove any dirt or debris from around the brake fluid reservoir cap.
Clean the area to prevent contamination of the brake fluid.

3. Top Off Brake Fluid

Tools Required: Funnel, brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Remove the cap from the brake fluid reservoir.
Using a funnel, carefully pour the appropriate brake fluid into the reservoir until it reaches the "MAX" fill line.
Ensure that no contaminants enter the reservoir during this process.
Replace and tighten the reservoir cap securely.

4. Check for Leaks

Visually inspect all brake lines, calipers, and the master cylinder for any signs of leaks or damage.
If any leaks are found, identify the source and proceed with necessary repairs or part replacements.

5. Test the Brake System

Start the vehicle and pump the brake pedal several times to ensure proper fluid circulation and brake function.
Check the brake warning light; it should turn off if the issue is resolved.
