Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Raise the vehicle using a jack and secure with jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; support it to avoid stress on the brake line.
Remove old brake pads from the caliper bracket.
Check the anti-rattle clips and replace if necessary.
Install new brake pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotor condition; if warped or scored, remove the rotor by taking off the retaining screws (if applicable).
Clean hub surface before installing new rotors.
Install new rotors, ensuring they are secured properly.

5. Reassemble Braking Components

Reattach the caliper over the new brake pads and rotor.
Tighten caliper bolts to the manufacturer's specified torque (typically around 20-30 ft-lbs).
Reinstall the wheel and tighten lug nuts in a crisscross pattern.

6. Final Checks

Lower the vehicle and remove jack stands.
Check brake fluid level and top off if necessary.
Pump the brake pedal several times to ensure pads seat properly.
