Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Safety glasses and gloves are recommended.

2. Remove Wheel

Use a lug wrench to loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and secure it on jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Using a dial indicator, measure the run-out of the rotor. Replace if warped beyond specifications (usually over 0.002 inches).
If replacement is needed, remove the caliper by unbolting it from the bracket and hanging it securely (do not let it dangle by the brake line).
Remove the rotor from the hub by unbolting or using a hammer to gently tap it off if it is stuck.
Install the new rotor and torque the bolts to the manufacturer's specifications (typically 80-100 ft-lbs).

4. Inspect and Replace Brake Pads

Check brake pad thickness; replace if below 3mm.
Remove the old pads and inspect the caliper for wear.
Apply brake grease to the backing of the new pads to reduce noise and ensure smooth operation.
Install new pads in the caliper bracket.

5. Reassemble and Test

Reinstall the caliper over the new pads and tighten bolts to the manufacturer's torque specifications.
Place the wheel back on, hand-tighten the lug nuts, and then lower the vehicle.
Torque the lug nuts to the manufacturer's specifications (typically 100-120 ft-lbs).
