Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and the engine is off.
Lift the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set (typically 12mm or 14mm).
- Carefully slide the caliper off the rotor; support it with a bungee cord to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly aligned in the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- If rotors are worn, remove them by unscrewing the rotor retaining screws (if applicable) and sliding the rotor off the hub.
- Clean the hub surface with a wire brush.
- Install new rotors, making sure they are seated properly on the hub.

5. Reassemble Brake Components

Reattach the caliper over the new pads, and secure it with the caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs for Volvo).
Pump the brake pedal a few times to ensure proper seating of the brake pads.
