Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a torque specification chart.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Use the lug wrench to loosen the lug nuts on the wheels.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness; replace if less than 3mm.
- Look for uneven wear or cracking.
Replace Brake Pads:
1. Remove the caliper by unscrewing the caliper bolts.
2. Slide the caliper off the rotor and hang it using a bungee cord (do not let it dangle on the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Apply brake cleaner to the caliper bracket and rotor.
5. Install new brake pads into the caliper bracket.
6. Reinstall the caliper over the new pads and secure with caliper bolts.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for scoring, warping, or excessive rust.
Replace Rotors:
1. If the rotor is damaged, remove the caliper bracket by unscrewing the bracket bolts.
2. Slide the rotor off the hub.
3. Clean the hub surface with brake cleaner.
4. Install the new rotor onto the hub, ensuring it sits flush.
5. Reinstall the caliper bracket and torque to specifications.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Remove the jack stands and lower the vehicle.
Torque the lug nuts to the manufacturer's specifications.
