Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during brake work.

2. Inspect Brake Components

Remove the wheel:
- Use a socket set to remove lug nuts.
- Lift the vehicle with a jack and secure it with jack stands.
Inspect brake pads:
- Measure pad thickness; replace if below manufacturer's specifications.
Inspect brake rotors:
- Check for warping using a dial indicator; replace if warped beyond tolerance (typically 0.002 inches).

3. Replace Worn Components

If brake pads or rotors are worn:
- Remove the caliper by unscrewing the caliper bolts with a socket.
- Slide out the old brake pads and replace them with new ones.
- For rotors, remove the old rotor and install the new rotor, ensuring it's properly seated.
- Torque caliper bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).

4. Reassemble and Recheck

Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
Lower the vehicle and reconnect the battery.

5. Final Inspection

Check for any leaks from brake lines or calipers.
Ensure that there are no obstructions or loose parts around the braking system.
