Solution

1. Preparation

Gather necessary tools and parts.
Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, socket set, and safety goggles.
Park the vehicle on a level surface and engage the parking brake.

2. Lift Vehicle and Remove Wheels

Use the jack to raise the vehicle and secure it with jack stands.
Remove the wheel using the lug wrench.
Set the wheel aside in a safe location.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake cleaner.
Remove the caliper bolts with a socket wrench and slide the caliper off the rotor.
Inspect brake pads for wear; if the friction material is less than 3mm, replace them.
If replacing, use brake cleaner to clean the caliper bracket and rotor.
Install new brake pads by sliding them into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, they need replacement.
Remove the rotor by unscrewing the retaining screws or caliper bracket if needed.
Install new rotors, ensuring they are properly seated.
Use a torque wrench to tighten any retaining screws to the manufacturer's specifications.

5. Reassemble Braking Components

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Carefully remove jack stands and lower the vehicle to the ground.
Tighten lug nuts in a star pattern to the specified torque.
Conduct a test drive to ensure that the noise is resolved and brakes are functioning properly.
