Solution

1. Preparation

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

2. Inspect Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Remove the cap and visually check the fluid level against the "MIN" and "MAX" markings.
- If fluid is low, proceed to refill using the appropriate brake fluid type (DOT 4 for most Volvos).
Replace the cap securely after inspection.

3. Check for Leaks

Visually inspect all brake lines and components for signs of fluid leakage.
- Pay close attention to connections at the master cylinder and brake calipers.
If leaks are found, identify the source and proceed with the necessary repairs (e.g., replacing hoses or seals).

4. Replace Brake Fluid (if necessary)

If the fluid is contaminated (dark or murky), flush the brake fluid system:
- Attach a brake bleeder kit to the brake bleeder valve on the furthest caliper.
- Open the valve and pump the brake pedal until clean fluid flows out.
- Repeat for each brake caliper, ensuring to keep the reservoir filled.
- Close all bleeder valves securely.

5. Test and Confirm Repair

Re-test the brake system by pressing the brake pedal to ensure it feels firm.
Start the vehicle and observe if the warning light has turned off.
