Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported using jack stands.
Disconnect the battery to ensure safety while working on electrical components.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Check the thickness of the brake pads; replace if worn below 3 mm.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the backing of the new pads.
- Install new brake pads in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for any grooves or warping on the rotor surface.
Replace Rotors:
- If damaged, remove the rotor by unscrewing the retaining screws if present.
- Install new rotors, ensuring they are seated properly.
- Torque the rotor screws to the manufacturer's specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque caliper bolts to manufacturer specifications.
Reattach the wheel and torque lug nuts in a star pattern.
Lower the vehicle back to the ground.
