Solution

1. Preparation

Tools Required: Jack stands, lug wrench, torque wrench, C-clamp or brake caliper tool, socket set, and screwdrivers.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Wear safety goggles and gloves.

2. Lift the Vehicle

Use the jack to lift the rear of the vehicle.
Secure the vehicle with jack stands for safety.
Remove the rear wheels using the lug wrench.

3. Remove Brake Caliper

Locate the caliper bolts and remove them using the socket set.
Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line; support it with a bungee cord or similar tool.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare the new pads with the old ones to ensure correct size.
Apply brake grease to the backing of the new pads to prevent squeaking.
Install the new brake pads into the caliper bracket.

5. Compress the Caliper Piston

Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing to accommodate the new, thicker pads.
Ensure the piston is fully seated and level.

6. Reinstall Brake Caliper

Slide the caliper back over the new brake pads.
Reinstall and tighten the caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs for Volvo XC90).

7. Reassemble and Lower the Vehicle

Reinstall the rear wheel and tighten the lug nuts in a criss-cross pattern to the specified torque (typically around 100-110 ft-lbs).
Lower the vehicle off the jack stands.

8. Final Check

Pump the brake pedal several times to ensure the brake pads seat properly.
Check the brake fluid level and top off if necessary.
