Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

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

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the brake pads.
- Inspect the pads for wear; replace if less than 1/8 inch thickness.
Brake Rotors:
- Check the surface of the rotors for grooves or scoring.
- If damaged, replace the rotors.
- Measure the thickness with a micrometer to ensure they meet manufacturer specifications.

4. Replace Brake Pads/Rotors (if necessary)

If brake pads or rotors are worn, install new parts:
- For brake pads, align them with the caliper bracket and push them in place.
- For rotors, slide the new rotor onto the hub, ensuring it is seated properly.

5. Reassemble Brake Components

Reattach the caliper over the new pads/rotors.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern.

6. Final Checks

Lower the vehicle and remove jack stands.
Pump the brake pedal a few times to seat the pads against the rotors.
Check brake fluid levels and top off if necessary.
