Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making the noise.
Secure the vehicle on jack stands to ensure stability.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Keep the lug nuts in a safe place for reinstallation.

4. Inspect Brake Components

Remove the brake caliper by loosening the caliper bolts with a socket set.
Carefully slide the caliper off the rotor and suspend it using a bungee cord or similar tool to avoid strain on the brake line.
Remove the brake pads from the caliper bracket and inspect for wear. Replace if they are worn down to the indicator.

5. Replace or Resurface Rotors

If the rotors are scored or warped, they should either be resurfaced or replaced.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new or resurfaced rotors by reversing the removal steps, ensuring they are properly seated.

6. Reassemble Brake Components

Install new brake pads into the caliper bracket.
Reattach the brake caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque (usually around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground using the jack.
Tighten the lug nuts to the specified torque (usually around 75-85 ft-lbs) in a crisscross pattern.
