Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety gloves and goggles.

2. Inspect and Fill Brake Fluid

Tools Required: Brake fluid (DOT 4 recommended for Volvo XC60), clean cloth, funnel
Open the hood and locate the brake fluid reservoir.
Check the fluid level against the markings on the reservoir; if low, proceed to fill.
Clean the reservoir cap and area around it to prevent contamination.
Using a funnel, carefully add the appropriate brake fluid until it reaches the "Full" mark.
Securely close the reservoir cap.

3. Check for Leaks

Inspect brake lines and hoses for any signs of wear or damage.
Check the master cylinder and brake calipers for any leaks.
If any leaks are found, mark the location for repairs.

4. Inspect Brake Components

Remove the wheel to access the brake components if necessary.
Check the brake pads for thickness and replace if below manufacturer's specifications.
Inspect rotors for scoring or excessive wear.

5. Test the Brake System

After refilling fluid and inspecting components, start the vehicle.
Pump the brake pedal to ensure it feels firm.
Take the vehicle for a short test drive to confirm braking effectiveness.
