Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface.
Engage the parking brake and wear safety glasses.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Remove Brake Components

Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Carefully lift the caliper off the rotor and support it using a bungee cord.
- Slide out the brake pads and inspect their thickness.
Brake Rotors:
- Remove the rotor if it shows signs of severe damage or wear.
- If necessary, use a hammer to gently tap the rotor off the hub.

4. Replace or Resurface Components

Brake Pads:
- If worn, install new brake pads, ensuring they are compatible with your model.
Brake Rotors:
- If the rotors are damaged, replace them; if they’re still usable but slightly worn, consider having them resurfaced.

5. Reassemble Brake Components

Place the new or resurfaced rotor onto the hub.
Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specified torque (typically around 25-35 Nm).

6. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts, then lower the car to the ground.
Use the lug wrench to tighten the lug nuts to the recommended torque (usually around 100 Nm).

7. Brake System Check

Pump the brake pedal several times to ensure the caliper seats correctly and the brake pads are adjusted.
Check brake fluid levels; top off if necessary.
