Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel Assembly

Use a lug wrench to loosen the lug nuts on the affected wheel.
Raise the vehicle with a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Use a dial indicator to check for rotor runout. If runout exceeds specifications, replace rotors.
- If rotors show signs of wear but are within limits, consider resurfacing.
Inspect Brake Pads:
- Remove the caliper by unscrewing the caliper bolts with a socket set.
- Check the brake pad thickness. Replace if less than 3mm.
Reassemble:
- Reinstall the caliper with the new pads and torque caliper bolts to manufacturer specifications (typically around 25-35 ft-lbs).
- Place the wheel back on and hand-tighten the lug nuts.

4. Recheck Alignment and Suspension

Inspect suspension components for any play or damage; replace any worn parts.
If necessary, perform a wheel alignment to ensure proper handling.

5. Final Assembly

Lower the vehicle and torque the lug nuts in a crisscross pattern to the manufacturer’s specification (usually around 75-85 ft-lbs).
Reconnect the battery.
