Solution

1. Preparation

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

2. Remove Wheel

Loosen lug nuts using a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket set and slide the caliper off the rotor.
Inspect the brake pads; if worn below the manufacturer’s specifications, replace them.
For replacement, remove the old pads and install new ones, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotor surface for grooves or damage. If necessary, replace them.
To replace, remove the rotor by unscrewing the retaining screws or bolts.
Install the new rotor, ensuring it is securely fastened.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and tighten the caliper bolts to the manufacturer's torque specifications.
Reattach the wheel, hand-tighten the lug nuts, and lower the vehicle.
Once on the ground, torque the lug nuts to the manufacturer's specifications.

6. Test the Brakes

Press the brake pedal several times to seat the pads against the rotors.
Conduct a test drive to ensure proper brake function and listen for any abnormal noises.
