Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, caliper tool, torque wrench, and a dial indicator (if checking rotor runout).
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Remove Wheel

Use the lug wrench to loosen the lug nuts slightly before jacking up the vehicle.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Rotors

Check the rotor surface for grooves or discoloration.
- If warped or damaged, proceed to replace the rotors.
- Use the dial indicator to measure runout; if it exceeds manufacturer specifications, replace rotors.

4. Replace Brake Pads

If brake pads are worn down (less than 3mm), replace them.
Remove the caliper bolts and slide the caliper off the rotor.
Remove the old pads and install new pads, ensuring they are correctly oriented.

5. Reassemble Components

Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and use the torque wrench to torque the lug nuts to manufacturer specifications.

6. Test Drive

After completing the above steps, conduct a test drive to ensure the shaking has been resolved.
