Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Lift the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Inspect the wheel for any signs of damage or debris.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the brake rotor.
Remove old brake pads from the caliper bracket.
Inspect the condition of the brake pad shims; replace if worn.
Insert new brake pads into the caliper bracket ensuring correct orientation.

4. Check and Replace Brake Rotors (if necessary)

If rotors are scored or worn beyond specification, remove them by unbolting from the hub.
Clean the mounting surface on the hub to ensure proper seating.
Install new rotors, ensuring proper alignment and torque to manufacturer specifications.

5. Reassemble Braking System

Reattach the caliper over the new brake pads, ensuring it slides smoothly.
Torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and torque lug nuts in a crisscross pattern to recommended values.

6. Final Check

Lower the vehicle back to the ground.
Pump the brake pedal several times to seat the new pads.
Perform a test drive to confirm the noise has been resolved.
