why does my Volvo XC90 make a squealing noise when braking?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure vehicle is on a flat surface and securely lift it using a jack and jack stands.
• Wear safety glasses and gloves.

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

• Inspect Brake Pads:

  • Check the thickness; if less than 3mm, replace them.

• Remove Old Brake Pads:

  • Use a socket set to remove the caliper bolts.
  • Carefully slide the caliper off the rotor.
  • Remove old brake pads from the caliper bracket.

• Install New Brake Pads:

  • Apply brake grease to the backing of the new pads (if required).
  • Place the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

• Check Rotor Condition:

  • If rotors are scored or warped, they should be replaced.

• Remove Caliper Bracket:

  • Remove the caliper bracket bolts with a socket set.
  • Take off the bracket and rotor.

• Install New Rotor:

  • Clean the hub surface with brake cleaner.
  • Install the new rotor onto the hub.
  • Reinstall the caliper bracket and torque to manufacturer specifications.

5. Reassemble and Test

• Reinstall the caliper over the new brake pads and torque bolts to specifications.
• Reinstall the wheel and torque lug nuts in a star pattern.
• Lower the vehicle and pump the brake pedal to seat the pads.
