how can I tell if my Volvo XC90 brake pads need replacing?

Solution

1. Preparation

• Gather tools: jack, jack stands, wheel chocks, lug wrench, torque wrench, caliper gauge.
• Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Lift the Vehicle

• Use the lug wrench to slightly loosen the lug nuts on the wheel where you are inspecting the brake pads.
• Jack up the vehicle and secure it with jack stands.
• Remove the wheel to access the brake assembly.

3. Inspect Brake Pads

• Visually check the brake pads for thickness. Replace if they are less than 3mm thick.
• Look for any signs of uneven wear or damage like cracks or excessive glazing.
• If equipped, check the wear indicator for contact with the rotor, which indicates replacement is needed.

4. Replace Brake Pads (if necessary)

• Remove the caliper by unbolting it from the bracket. Use a torque wrench for proper reinstallation later.
• Slide the old brake pads out of the caliper bracket.
• Install new brake pads into the caliper bracket, ensuring they are positioned correctly.
• Reinstall the caliper over the new pads and bolt it securely.

5. Reassemble and Test

• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle and then torque the lug nuts to the manufacturer’s specification.
• Test the brakes by gently applying pressure and ensuring they engage smoothly.
