Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a flat surface.
Wear gloves and safety glasses.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Remove the reservoir cap carefully.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.

3. Add Brake Fluid

If the fluid is low, use the appropriate brake fluid type (typically DOT 3 or DOT 4 for most Volvos).
Clean the cap and surrounding area before opening to prevent contamination.
Pour brake fluid into the reservoir until it reaches the "MAX" mark.
Replace the reservoir cap securely.

4. Inspect for Leaks

Visually inspect all brake lines, calipers, and the master cylinder for any signs of leaks.
If leaks are found, mark the locations for repair.

5. Brake System Maintenance

If brake pads or rotors show signs of wear, replace them as necessary.
Ensure all components are properly torqued according to manufacturer specifications.

6. Test the Brake System

Conduct a test drive to ensure the brakes function correctly.
Monitor the brake fluid warning light to verify it has turned off.
