Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Remove the Wheels

Lift the vehicle using a jack and secure with jack stands.
Use a lug wrench to remove the wheel nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; if below 3mm, replace them.
Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor; support it with a bungee cord to avoid straining the brake line.
Remove Old Brake Pads:
- Slide out the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the back of the new pads to prevent squeaking.
- Slide the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- If the rotor is worn, remove any retaining screws and slide the rotor off the wheel hub.
Install New Brake Rotor:
- Position the new rotor onto the wheel hub.
- Secure with retaining screws if applicable.

5. Reassemble the Braking System

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper mounting bolts to the manufacturer's specified torque (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and remove jack stands.
Tighten the lug nuts to the specified torque (typically around 80-100 ft-lbs).
Pump the brake pedal a few times to ensure proper pad seating.
