Solution

1. Preparation

Gather tools and materials:
- Brake fluid
- Wrench set
- Brake cleaner
- Socket set
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" markings.
3. If low, add the appropriate brake fluid (DOT 4 for most Volvo models).
4. Replace the cap securely.

3. Inspect Brake System Components

Sub-steps:
1. Visually inspect the brake lines for any signs of leaks or damage.
2. Check the brake calipers and hoses for any fluid leakage.
3. Remove the wheel to access the brake pads and rotors.
4. Measure the thickness of the brake pads; replace if below manufacturer specifications (typically below 3 mm).
5. Inspect the brake rotors for scoring or warping; replace if damaged.

4. Check Brake Light Switch

Sub-steps:
1. Locate the brake light switch, usually mounted on the brake pedal assembly.
2. Test the switch with a multimeter to ensure it is functioning properly.
3. Replace the switch if it is defective.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and tighten lug nuts to the specified torque (typically 80-100 ft-lbs).
2. Lower the vehicle and start the engine.
3. Press the brake pedal to ensure it feels firm and responsive.
