why does my Volvo XC60 536 (2017-Present) make a grinding noise when braking

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.
• Wear safety goggles and gloves for protection.

2. Remove Wheel

• Loosen the lug nuts on the affected wheel using a socket wrench.
• Raise the vehicle with a jack and secure it with jack stands.
• Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

• Inspect Brake Pads:
  • Remove the caliper bolts with a socket wrench.
  • Carefully slide the caliper off the rotor without disconnecting the brake line.
  • Check the thickness of the brake pads. If they are worn down to less than 3mm, they should be replaced.
• Replace Brake Pads:
  • Remove the old brake pads from the caliper bracket.
  • Install new brake pads in the caliper bracket, ensuring they are positioned correctly.
  • Apply brake grease to the backing of the new pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

• Inspect Brake Rotors:
  • Check the rotor surface for deep grooves or scoring.
  • Measure rotor thickness with a micrometer; if below the minimum specifications, replace them.
• Replace Brake Rotors:
  • Remove the caliper bracket if necessary.
  • Unscrew and remove the rotor from the hub. If it is stuck, tap gently with a rubber mallet.
  • Install the new rotor, aligning it properly on the hub.

5. Reassemble and Test

• Reattach the caliper bracket and caliper, tightening bolts to the manufacturer’s torque specifications.
• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle and tighten the lug nuts to the specified torque.
• Pump the brake pedal several times to seat the new pads.
• Test drive the vehicle at low speed to ensure the brake system is functioning correctly.
