Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, dial indicator, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the brake caliper by unbolting it.
- Inspect the brake pads for thickness; replace if they are below the manufacturer’s specifications.
Brake Rotors:
- Check the rotor surface for grooves or discoloration.
- Use a dial indicator to measure rotor runout; if it exceeds manufacturer specifications, replace or resurface the rotors.

4. Reassemble and Test

If components are replaced, install new brake pads and rotors following the manufacturer’s torque specifications.
Reinstall the brake caliper and ensure it is properly secured.
Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer's specifications.
