Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical system.
Elevate the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; if less than 3mm, replace.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the brake pads.
- Remove the old brake pads and insert new pads, ensuring they are seated correctly in the caliper.

4. Inspect and Replace Brake Rotors

Inspect Brake Rotors:
- Check for grooves or warping on the rotor surface.
Replace Brake Rotors:
- Remove the rotor retaining screws if present.
- Slide the old rotor off the wheel hub.
- Install the new rotor, torquing the retaining screws to the manufacturer’s specifications.

5. Reassemble Components

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer’s torque specifications.
Reattach the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and tighten the lug nuts in a star pattern to ensure even pressure.
Reconnect the battery.
