Solution

1. Preparation

Gather necessary tools and parts.
Safely elevate the vehicle using a hydraulic jack and secure it with jack stands.
Ensure the vehicle is on a level surface.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts slightly while the wheel is still on the ground.
Raise the vehicle and remove the lug nuts completely.
Take off the wheel to access the brake system.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to check for rotor warping. If the runout exceeds the manufacturer's specification, replacement is necessary.
Replacement:
- If necessary, remove the brake caliper by unbolting it from the bracket.
- Remove the rotor by taking off the retaining screws (if applicable) and sliding it off the hub.
- Install the new rotor, ensuring it is seated properly.
- Reinstall the brake caliper and torque the bolts to the manufacturer’s specifications.

4. Inspect Brake Pads

Check the thickness of the brake pads. If they are worn beyond the manufacturer's specifications, replace them.
To replace:
- Remove the caliper as previously done.
- Slide out the old brake pads and insert the new pads, ensuring they are oriented correctly.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and properly torque the lug nuts to the specified value.

6. Test Drive

Perform a test drive to ensure the issue is resolved and monitor for any vibrations during braking.
