Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Lift the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads by aligning them with the caliper bracket.
Apply brake grease to the back of the new pads to reduce noise.

4. Inspect and Replace Rotors (if necessary)

Check the rotor surface for any grooves or damage. If worn, replace the rotors.
To remove the rotor, remove any retaining screws or clips.
Install the new rotor, ensuring it is seated properly against the hub.

5. Reassemble Brake 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 tighten the lug nuts in a crisscross pattern.

6. Final Checks

Lower the vehicle from the jack stands.
Pump the brake pedal to ensure proper brake pad seating.
Check brake fluid levels and top off if necessary.
