Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Wear safety gloves and goggles.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Carefully remove the brake caliper by loosening the caliper bolts with a socket set.
Suspend the caliper using a bungee cord or similar to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the old pads for wear; replace if thickness is below manufacturer specifications (usually 3mm or less).
Install new brake pads into the caliper bracket, ensuring they are seated properly.

4. Inspect and Resurface or Replace Rotors

Check the rotor surface for wear or damage. If warped or scored, consider resurfacing or replacing.
For resurfacing, use a brake lathe per manufacturer specifications.
If replacing, remove the rotor by unscrewing the retaining screws (if present) and sliding it off the hub.

5. Reassemble Components

Reinstall the rotor (if replaced) and ensure it is properly secured.
Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from jack stands and remove the jack.
Tighten the lug nuts to the manufacturer’s torque specifications in a crisscross pattern.
Pump the brake pedal several times to ensure the brake pads seat properly.
