Solution

1. Preparation

Tools Required:
- Socket set (including 7mm hex socket)
- Torque wrench
- Brake caliper tool (or C-clamp)
- OBD-II scanner (if needed)
- Safety goggles and gloves
Sub-steps:
- Park the vehicle on a flat surface and engage the parking brake.
- Gather all necessary tools and replacement brake pads.
- Wear safety goggles and gloves to protect yourself.

2. Remove the Wheel

Sub-steps:
- Loosen the wheel lug nuts slightly while the vehicle is on the ground.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Caliper

Sub-steps:
- Locate and remove the caliper bolts using the 7mm hex socket.
- Carefully slide the caliper off the rotor and support it with a bungee cord or a hook to avoid putting stress on the brake line.

4. Replace the Brake Pads

Sub-steps:
- Remove the old brake pads from the caliper bracket.
- Use the brake caliper tool or C-clamp to compress the caliper piston back into the caliper housing to make room for the new pads.
- Install the new brake pads into the caliper bracket, ensuring they are positioned correctly.

5. Reassemble the Brake System

Sub-steps:
- Reinstall the brake caliper over the new pads and align it with the rotor.
- Tighten the caliper bolts to the manufacturer's specified torque (typically around 30 Nm or as specified in the service manual).
- Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Sub-steps:
- Carefully lower the vehicle back to the ground.
- Once on the ground, use the torque wrench to tighten the lug nuts to the specified torque (usually around 110 Nm).

7. Final Checks

Sub-steps:
- Pump the brake pedal several times to ensure proper seating of the pads and to restore brake pressure.
- Check the brake fluid level and add fluid if necessary.
