Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a level surface, and set the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the brake rotor.
Remove the old brake pads; if they are worn down, replace them with new pads.
Apply brake grease to the back of the new pads to reduce noise and vibration.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for scoring or damage; if damaged, replace them.
If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are properly seated.

5. Reassemble Braking Components

Reinstall the caliper over the new pads and rotor.
Torque caliper bolts to the manufacturer's specifications (generally around 25-30 lb-ft).
Reinstall the wheel and torque lug nuts in a star pattern to the manufacturer's specification (usually around 75-80 lb-ft).

6. Final Checks

Lower the vehicle off the jack stands and remove the jack.
Pump the brake pedal several times to ensure proper seating of the pads.
