Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect Brake Components

Remove the brake caliper by loosening the caliper bolts with a socket wrench.
Take off the caliper and hang it using a bungee cord to avoid strain on the brake line.
Inspect brake pads for uneven wear and check the rotor surface for warping.

4. Resurface or Replace Rotors

If rotors are warped, resurface them using a brake lathe or replace with new rotors if thickness is below minimum specification.
Ensure rotors are clean and free of debris before installation.

5. Replace Brake Pads (if necessary)

If brake pads are worn unevenly, replace them with new pads.
Apply brake pad grease to the backing plate to reduce noise and improve performance.

6. Reassemble Components

Reattach the brake caliper and tighten bolts to manufacturer specifications.
Reinstall the wheel and lug nuts, tightening in a star pattern to ensure even pressure.

7. Lower Vehicle and Test

Remove jack stands and lower the vehicle.
Pump the brake pedal a few times to seat the pads before driving.
