Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the vehicle and place jack stands securely.
Remove the wheel using a socket set.

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using a socket.
Carefully slide the caliper off the brake rotor; support it with a bungee cord or rope to prevent strain on the brake line.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare new pads with old ones to ensure proper fit.
Install the new brake pads in the caliper bracket, ensuring they are seated correctly.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and tighten the mounting bolts to the manufacturer’s specified torque (usually around 75-85 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque (usually 75-80 ft-lbs) in a star pattern.

7. Final Checks

Pump the brake pedal several times to seat the new pads against the rotors.
Check for leaks around the brake caliper and ensure everything is secure.
