Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear appropriate safety gear (gloves, goggles).

2. Remove Wheel

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

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 below manufacturer's specifications (typically 3mm).
Replace Brake Pads:
- If replacement is necessary, remove the old pads.
- Install new brake pads, ensuring they are oriented correctly.
- Apply anti-squeal lubrication to the back of the pads if recommended.

4. Inspect and Replace Brake Rotors (if necessary)

Check the surface of the rotors for scoring or warping.
If replacement is needed, remove the rotor by unscrewing the retaining screws.
Install new rotors, ensuring they are clean and free of debris.
Torque rotor screws to manufacturer specifications.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer's torque specification.
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and tighten the lug nuts in a star pattern.
Pump the brake pedal a few times to seat the pads against the rotor.
