Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheel

Loosen the lug nuts on the wheel where the noise is occurring.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the brake rotor without stretching the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any damage or leaks.
If the pads are worn down, install new brake pads according to the manufacturer's specifications.
- Ensure the pads are oriented correctly (inside vs. outside).

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or excessive wear.
If the rotors are damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Replace with new rotors, ensuring they are properly aligned and seated.

5. Reassemble Braking System

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque.

6. Final Steps

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the new pads.
Check brake fluid level and top off if necessary.
