Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set, caliper tool, and dial gauge.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported before starting work.

2. Remove Wheel

Loosen lug nuts while the vehicle is on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Check the brake rotors using a dial gauge for runout; if the runout exceeds specifications, replace the rotors.
If necessary, remove the caliper by unbolting it and hanging it safely (do not let it dangle by the brake line).
Remove the old rotors and install new ones, ensuring they are clean and properly seated.
Torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check the caliper piston for proper retraction; use a caliper tool if needed.
Install new brake pads, ensuring they are compatible with the rotors.
Reattach the caliper and torque the bolts to the specified value.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to the specified torque.
Test drive the vehicle to ensure the vibration has been resolved.
