Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure with jack stands to ensure stability.

3. Inspect Brake Components

Remove Wheel:
- Use a lug wrench to loosen and remove the wheel bolts.
- Take off the wheel and set it aside.
Inspect Brake Pads and Rotors:
- Visually inspect brake pads for thickness; replace if worn below manufacturer's specifications.
- Check rotors for grooves, cracks, or warping. Use a runout gauge to measure rotor runout.

4. Replace Brake Rotors and Pads (if necessary)

Remove Caliper:
- Unbolt the caliper from the bracket using a socket set.
- Support the caliper with a bungee cord or wire; do not let it hang by the brake line.
Remove Brake Pads:
- Slide out the old brake pads from the caliper bracket.
Remove Rotors:
- Unbolt and remove the rotor if it is warped or damaged.
Install New Rotors and Pads:
- Place the new rotor onto the hub, ensuring it is seated properly.
- Install new brake pads into the caliper bracket.
- Reattach the caliper and torque the bolts to the manufacturer's specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug bolts.
Lower the vehicle and then torque the lug bolts to the specified value.
