Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Engage the parking brake and wear safety glasses.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the shaking is felt.
Support the vehicle securely with jack stands.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Inspect the brake components visually for any obvious signs of wear or damage.

4. Inspect and Replace Brake Rotors

Inspection:
- Use a run-out gauge to measure rotor warping. If run-out exceeds manufacturer specifications, proceed to replace.
Replacement:
- Unbolt the caliper from the bracket using a socket set and hang it securely (do not let it dangle by the brake line).
- Remove the rotor from the hub. If rusted, use a hammer to gently tap it free.
- Install the new rotor and ensure it is seated properly.
- Reinstall the caliper over the new rotor and tighten bolts to the specified torque.

5. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the pads' contact points.
Install the new brake pads and ensure they are secured properly.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.
Repeat the process for the other side if applicable.
