Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear safety goggles and gloves.

2. Remove Wheel

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

3. Inspect and Replace Brake Rotors

Tools Required: Brake rotor tool, torque wrench, socket set.
Inspect the brake rotors for warping using a micrometer. If warped beyond manufacturer specifications, proceed to replace.
Remove the caliper by unscrewing the bolts and securing it with a bungee cord (do not let it hang by the brake line).
Remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
Install the new rotor, ensuring it is seated correctly.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check the caliper for signs of sticking or damage; replace if necessary.
Clean the caliper bracket and install new brake pads in the correct orientation.
Reinstall the caliper over the new pads and torque bolts to manufacturer specifications.

5. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Use a torque wrench to tighten the lug nuts to the specified torque.

6. Test Drive

Conduct a test drive to ensure that the steering wheel vibrations during braking have been resolved.
