Solution

1. Preparation

Gather Tools:
- Jack and jack stands
- Lug wrench
- Brake caliper tool
- Torque wrench
- Safety goggles and gloves

2. Lift the Vehicle

Sub-steps:
- Park the vehicle on a level surface and engage the parking brake.
- Loosen the lug nuts slightly without removing them.
- Use the jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the wheel to access the brakes.

3. Remove Brake Caliper

Sub-steps:
- Locate the caliper mounting bolts and remove them using the appropriate socket.
- Carefully slide the caliper off the brake rotor and suspend it using a bungee cord or rope to avoid damaging the brake line.

4. Inspect and Replace Brake Pads

Sub-steps:
- Check the thickness of the brake pads; replace if they are less than 1/8 inch.
- Remove the old brake pads by sliding them out of the caliper bracket.
- Install new brake pads into the caliper bracket, ensuring they are properly seated.

5. Reassemble the Brake Components

Sub-steps:
- Compress the caliper piston using a brake caliper tool to fit over the new pads.
- Reattach the caliper over the new brake pads and secure it with the mounting bolts.
- Tighten the caliper bolts to the manufacturer's specified torque (usually around 20-25 ft-lbs).

6. Reinstall Wheel and Lower Vehicle

Sub-steps:
- Place the wheel back on the hub and hand-tighten the lug nuts.
- Lower the vehicle from the jack stands and then fully tighten the lug nuts in a crisscross pattern to ensure even torque.
