Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a lug wrench and take off the wheel.

3. Inspect and Remove Brake Components

Sub-steps:
- Inspect the brake pads for thickness. If they are below 3mm, they need replacement.
- Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
- Hang the caliper using a wire or bungee cord to avoid stressing the brake line.
- Remove the brake pads from the caliper bracket.

4. Replace Brake Pads

Sub-steps:
- If necessary, replace brake pads with new ones, ensuring they are compatible with the XC90 model.
- Apply brake grease to the back of the new pads to reduce noise.
- Reinstall the brake pads into the caliper bracket.

5. Inspect and Clean Rotors

Sub-steps:
- Check rotors for any signs of damage or excessive wear.
- If needed, resurface or replace the rotors.
- Clean the rotor surface with brake cleaner to remove any grease or dust.

6. Reassemble Brake Components

Sub-steps:
- Reinstall the caliper over the new pads.
- Tighten the caliper bolts to the manufacturer’s torque specifications (typically around 25-30 ft-lbs).
- Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Check

Lower the vehicle off the jack stands and tighten the lug nuts in a crisscross pattern to the specified torque (typically 80-100 ft-lbs).
