Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Wear safety gloves and goggles.

2. Raise the Vehicle

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

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Set the wheel aside in a safe location.

4. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are less than 3mm, they need replacement.
Remove: Unbolt the caliper using a socket set; hang it using a bungee cord to avoid stress on the brake line.
Replace: Remove old brake pads and install new pads, ensuring they are properly seated in the caliper bracket.

5. Inspect and Resurface/Replace Rotors

Inspect: Check the rotors for grooves, scoring, or warping.
Resurface: If minor damage, use a brake lathe to resurface the rotors.
Replace: If heavily damaged, remove the rotor by unbolting it from the hub and install a new rotor.

6. Reassemble Brake Components

Reattach the caliper and secure it with the bolts to the manufacturer's torque specifications (typically around 20-25 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground and fully tighten the lug nuts in a star pattern to ensure even pressure.
