Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove Wheel Assembly

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts with a socket set and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts with a socket set.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads and inspect for wear. Replace if worn below specifications (usually 3mm).
- Install new brake pads, ensuring they are properly seated.
Brake Rotors:
- Check the rotor for grooves or scoring. If damaged, remove the rotor by unscrewing the rotor retaining screws.
- Install a new rotor, ensuring it's securely fastened and properly aligned.

4. Reassemble Components

Reattach the caliper over the new brake pads.
Tighten the caliper bolts to the manufacturer's torque specifications (usually around 25-35 ft-lbs, depending on the model).
Reinstall the wheel and lug nuts, tightening them in a criss-cross pattern to the recommended torque.

5. Final Checks

Reconnect the battery.
Lower the vehicle from the jack stands.
Check brake fluid levels and top off if necessary.
