Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and possibly new brake pads and rotors.
Safety Warning: Ensure the vehicle is securely lifted and stable on jack stands before working on it.

2. Remove Wheel

Loosen the lug nuts using the lug wrench.
Raise the vehicle with the jack and secure it with jack stands.
Remove the lug nuts and then the wheel to access the braking components.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the caliper by unscrewing the caliper bolts with a socket.
- Slide the caliper off the rotor and support it (do not let it dangle from the brake line).
- Check the thickness of the brake pads. If less than 3mm, replace them.
Replace Brake Pads:
- Remove old pads from the caliper bracket.
- Apply brake grease to the back of the new pads and install them in the caliper bracket.
Inspect and Replace Brake Rotors (if necessary):
- Check the surface of the rotor for grooves or scoring.
- If damaged, remove the rotor by unscrewing the retaining screws (if present) and pulling it off the hub.
- Install the new rotor, ensuring it is seated properly.

4. Reassemble and Torque

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specifications (typically around 25 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Final Check

Lower the vehicle off the jack stands using the jack.
Tighten the lug nuts in a crisscross pattern to the manufacturer's torque specification (typically around 120 Nm).
