Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

Use a socket set to loosen lug nuts while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and inspect the brake pads for uneven wear.
- Replace if necessary using new pads that meet OEM specifications.
Inspect Brake Rotors:
- Measure rotor thickness with a micrometer to check for wear.
- If warped (more than 0.002 inches deviation), replace the rotors.
- Clean the rotor surfaces with brake cleaner before installation.

4. Reassemble Components

Reinstall the caliper over the new pads and torque caliper bolts to manufacturer specifications (usually around 25-35 Nm).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use a torque wrench to tighten the lug nuts to the specified torque (typically 100-120 Nm).

5. Test Drive

Reconnect the battery.
Perform a test drive to confirm the vibration has been resolved and check for any abnormal noises.
