Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Safety Warnings: Ensure the vehicle is securely supported on jack stands before working underneath or removing wheels.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket.
Slide the caliper off the rotor and support it using a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the pads for wear; if they are worn down to the metal, they should be replaced.
Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotor for any scoring or excessive wear.
If the rotor is damaged, remove it by unbolting the caliper bracket and sliding the rotor off the hub.
Install a new rotor, ensuring it is centered properly.
Torque the rotor bolts to the manufacturer’s specifications.

5. Reassemble Braking Components

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

6. Final Checks

Lower the vehicle and tighten the lug nuts to the specified torque in a crisscross pattern.
Test the brake pedal for proper feel before driving.
