Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check for thickness; replace if worn down to 3mm or less.
Inspect Brake Rotors:
- Measure rotor thickness and check for warping using a runout gauge.
- If warped (more than 0.002 inches), replace the rotors.
Replace Brake Pads:
- Remove the caliper by unbolting it from the bracket.
- Slide the old pads out and replace them with new pads.
- Reinstall the caliper and torque the bolts to manufacturer specifications (usually around 20-30 ft-lbs).

4. Reassemble and Check Suspension

Reinstall the wheel and tighten the lug nuts in a criss-cross pattern to the specified torque (typically 100-150 ft-lbs).
Check suspension components for any signs of wear or damage, and replace as necessary.

5. Reinstall Wheel and Lower Vehicle

Lower the vehicle from the jack stands and remove the jack.
Perform a final check on lug nut torque.
