Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove Wheel

Loosen the lug nuts using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspection:
- Visually inspect the brake rotors for warping or scoring.
- Use a dial indicator to measure rotor runout.
Replacement:
- If rotors are warped, remove them by unscrewing the retaining screws.
- Install new rotors, ensuring they are properly aligned.
- Torque the retaining screws to manufacturer specifications.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads using a caliper tool.
If worn below acceptable limits, remove the caliper bolts and slide the caliper off the pads.
Replace with new brake pads, ensuring proper orientation and alignment.
Reattach the caliper and torque bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the specified value.
Reconnect the battery.
Test the brakes to ensure the shaking has been resolved.
