Solution

1. Preparation

Gather tools and parts: brake pads, rotors (if necessary), brake cleaner, jack and jack stands, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle depending on where the noise is originating.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket set.
Carefully slide the caliper off the rotor and support it without disconnecting the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads ensuring they are seated properly in the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for damage. If they are scored or warped, proceed to replace them.
Remove the rotor by unscrewing any retaining screws and gently pulling it off the hub.
Clean the hub surface with brake cleaner before installing the new rotor.
Install the new rotor and secure it with screws if applicable.

6. Reassemble Braking Components

Reattach the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer’s specified torque value (usually around 20-30 ft-lbs but check service manual for specifics).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle

Carefully lower the vehicle back to the ground and remove the jack stands.

8. Final Checks

Tighten lug nuts to the manufacturer’s specified torque value (typically 75-85 ft-lbs).
Pump the brake pedal a few times to seat the brake pads properly against the rotors.
