Solution

1. Preparation

Gather tools: socket set, torque wrench, brake cleaner, and a caliper gauge.
Ensure the vehicle is parked on a level surface with the parking brake applied.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper by loosening the caliper bolts.
- Slide the caliper off the rotor without disconnecting the brake line.
- Check the thickness of the pads; replace if worn below manufacturer specifications.
Replace Brake Pads:
- If replacement is needed, remove the old pads and install new pads.
- Apply brake grease to the back of the pads to prevent squeaking.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for damage. If scoring or warping is present, replace them.
To remove the rotor, remove any retaining screws and slide the rotor off the hub.
Install the new rotor, ensuring it is seated properly.

5. Reassemble and Torque Components

Reinstall the caliper over the new brake pads and rotor.
Tighten caliper bolts to manufacturer torque specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern.
