Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during repair.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the car is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Pads:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Check the thickness of the brake pads; if they are worn down to 3mm or less, they need replacement.
Replace Pads:
- If replacement is necessary, compress the caliper piston using a caliper tool.
- Remove the old brake pads and install new pads, ensuring they are properly positioned.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect the rotors for any signs of scoring or warping. If they show significant wear:
- Remove the caliper bracket by unscrewing the bolts.
- Slide the rotor off the hub; if stuck, tap gently with a rubber mallet.
- Install new rotors, ensuring they are clean and free of contaminants.

5. Reassemble Components

Reattach the caliper bracket and torque the bolts to the manufacturer’s specifications.
Slide the caliper back over the new pads and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts in a star pattern to ensure even pressure.
Reconnect the battery.
