Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are less than 3 mm, they need replacement.
Remove Old Brake Pads:
- Remove the caliper bolts using a socket.
- Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
- Remove the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of the new pads to prevent noise.
- Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors:
- If rotors are severely grooved or worn, they should be replaced.
Remove Rotors:
- Remove any retaining screws if present, and slide the rotor off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub and secure with screws.

5. Reassemble Braking Components

Slide the caliper back over the new brake pads and rotor.
Reinstall the caliper bolts and torque to manufacturer specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and lug nuts, and torque to manufacturer specifications (typically around 100-120 ft-lbs).

6. Final Checks

Lower the vehicle from the jack stands and remove the jack.
Pump the brake pedal several times to seat the new pads against the rotors.
