Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use wheel chocks to prevent movement.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; if they are below 3mm, replacement is necessary.
Remove Old Brake Pads:
- Use a socket set to remove the caliper bolts.
- Slide the caliper off the rotor and hang it securely without stressing 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.
- Place the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for any scoring, warping, or excessive wear.
Remove Rotors:
- Use a socket set to remove the rotor retaining screws (if present).
- Slide the rotor off the wheel hub.
Install New Rotors:
- Clean the new rotor with brake cleaner to remove any protective oil.
- Slide the new rotor onto the hub and secure it with screws.

5. Reassemble Brake Components

Reinstall Caliper:
- Slide the caliper over the new brake pads and rotor.
- Tighten the caliper bolts to manufacturer specifications (typically around 25-30 Nm).
Reattach Wheel:
- Place the wheel back on the hub.
- Hand-tighten lug nuts and then lower the vehicle to the ground.
Torque Lug Nuts:
- Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically 90-110 Nm).
