Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, dial indicator, torque wrench, and brake cleaner.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Raise the Vehicle

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors (if warped)

Use a dial indicator to measure the rotor's runout; if it exceeds specifications, replace the rotor.
Remove caliper bolts and slide the caliper off the rotor.
Remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Clean the hub surface with brake cleaner before installing the new rotor.
Install the new rotor, ensuring it is seated properly.

4. Inspect and Replace Brake Pads (if necessary)

Remove the caliper bracket bolts and remove the bracket.
Inspect the brake pads for wear; replace if the thickness is below specifications.
Install new brake pads, applying brake lubricant to the backing plates where necessary.
Reinstall the caliper bracket and torque bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts to the manufacturer's torque specifications.
